Expert Witness Corner: SIM Card Data Retrieval – The Essentials

The Importance Of SIM Cards:

There are more mobile telephones in the UK then there are people – this pervasive technology impacts on almost all areas of industry and life. Unsurprisingly, mobile communications have enabled old crime to be effected in new ways and mobile telephones are increasingly forming a part of criminal prosecutions, where linkages between individuals or evidence of being at the scene of the crime is provided by an analysis of the digital evidence available within the mobile phones.

At the heart of every mobile telephone is the Subscriber Identity Module (SIM), a small fingernail sized chip, responsible for service with a telecom network provider.

Digital Evidence From SIM Cards:

Despite limited memory capacity, the SIM contains a wealth of information that, when considered in context, can greatly aid lawyers in their case preparations:

• Stored telephone numbers/contacts.

• Listings of ‘Last Dialled Numbers’.

• Text messages received, sent, drafted or deleted.

• General location information from last use.

• References to overseas network providers that have been used.

Common Questions:

Q: Could the SIM card have been cloned?

A: SIM cards produced after June 2002 employ the COMPv2 algorithm which provides a number of technical and security safeguards to prevent unauthorised modification. Despite media reports, the cloning of modern SIM cards is an extremely rare practice.

Q: Can my PIN code be cracked?

A: SIM card information can be locked using a four digit ‘Personal Identification Number’. RIPA contains provisions to force disclosure of passwords, however, it is usually easier to request a ‘Phone Unlock Key’ (PUK), enabling PIN settings to over- ridden, from the Data Protection Officer (DPO) at the relevant network provider.

Q: PAYG SIMs are untraceable!

A: With ‘Pay As You Go’ (PAYG) there is no formal contract with a network provider (e.g. Orange) to enable a customer look-up, however, ‘Call Data Records’ (CDRs) are still available from the network provider, providing information as to patterns of communication, calls to/from, time/dates etc. By mapping this information to known acquaintances of the defendant, considering the evidence in the context of other material (such as messages recovered from the telephone handset) and undertaking Cell Site Analyses (CSAs)3 it is possible to prove/disprove ownership of a handset.

Q: Does the SIM reveal who I’ve been in touch with?

A: Even without the disclosure of Call Data Records (CDRs) from the network provider, the SIM provides a plethora of useful information relating to contacts in the form of ‘Last Numbers Dialled’ (LND) and sections of the ‘Contacts Directory’. Numbers that haven’t been saved may still show up in the LND.

Q: Can a telephone handset be uniquely identified?

A: Mobile phone handsets are assigned unique 15-digit numbers, known as the International Mobile Equipment Identifier (IMEI), which is passed to the network provider before communication services can be utilised. This serial number allows specific handsets that have been stolen or blacklisted to be blocked from a network irrespective of what SIM card is inserted. Defences suggesting that a given handset has been ‘found’ and is not owned by the suspect are unlikely to hold water if Call Data Records (CDRs) show a pattern of usage that indicate the owners identity.

Q: What about sending anonymous texts?

A: They are not really that anonymous… If they are being sent via an internet service, there is typically a log retained by the site provider as to the computer IP address that sent the specific message – this can ultimately be tied by to an Internet Service Provider (ISP), and in turn a specific subscriber. If anonymous texts have been sent from a mobile telephone – typically a PAYG handset/SIM – the uniquely assigned International Mobile Subscriber Identifier (IMSI) code embedded in the SIM can be used in concert with CDRs to provide compelling evidence as to the sender identity.

Q: Can deleted text messages & numbers be recovered?

A: Data content (especially multimedia formats) is primarily stored on the handset or on a removable memory stick. The general rule of thumb is that any data that has been deleted can be recovered, however, if it has been over-written it does make the process more complex and the chances of success reduce with every over-write.

Q: Is possession of multiple SIM cards indicative of wrongdoing?

A: Not at all – many individuals are discovering that they can benefit greatly from the free text and talk allowances granted on mobile phone contracts by having two or more SIMs (typically with different network providers). Adapters are available to connect multiple SIMs to a handset simultaneously.

Did you know?

The SIM card will often contain a reference to the last network base station that it communicated with before being disconnected from the telecoms network.

If the SIM card has been used overseas, it is possible to retrieve a reference code from the card that will indicate which national/regional network provider was used.

Language preferences can be stored on SIM cards – useful intelligence for investigators which can open up new avenues of enquiry.

Expert Witness Corner: Maximising Quantum – A Physiotherapist’s Role

Traditionally, personal injury cases involve a report from an orthopaedic consultant or general practitioner to help establish the nature of the medical condition and its causation and prognosis. An experienced clinical physiotherapist can offer a complete understanding of the whole process from first injury right the way through to recovery. Armed with this knowledge, a more thorough and wide-ranging report can be provided that will accurately reflect the extent and timing of patient recovery – essential when considering issues of quantum and future care costs.

Soft tissue injuries are injuries not involving bony damage such as fractures. They are often incurred as a result of whiplash or repetitive strain and, as the name implies, only involve damage to muscles, tendons, ligaments, fascia and nerves. The damage is usually invisible on x-rays and scans and can be detected only by skilled examination. Torn muscles, ligaments, nerves and cartilages may require a surgeon’s skills. But once this primary care has been administered, the client will invariably be referred to a physiotherapist. A physiotherapist can provide specific and individually tailored treatment aimed at assisting the body’s natural healing and restoring full function.

Examples of relevant soft tissue injuries include:

•Tendonitis
•Tenosynovitis
•Muscle strains
•Lifting injuries
•Lower back pain
•Epicondylitis
•Carpal tunnel syndrome
•Whiplash injuries
•Work-related upper limb disorders.

When examining issues of quantum and future costs, it is essential that a lawyer receives the whole picture: the exact nature of the injury, detail of treatment, likelihood of full recovery, timing of recovery, and an indication of future care costs, if any. An experienced physiotherapist in clinical practice has a wealth of relevant expertise.

A clinical physiotherapist is usually involved with a patient from presentation of the injury through to the end of rehabilitation. Treatment can be broadly divided into four stages:

1: Conducting a detailed specific examination to identify the body structures damaged and any loss of function.
2: Devising a treatment programme.
3: Implementing the treatment programme.
4: Seeing the patient through to the end of rehabilitation – hopefully back to ‘normality’.

The ‘hands-on’ nature of the patient–therapist relationship, plus the inevitably regular patient contact, give physiotherapists an enormous advantage when it comes to diagnosing and treating a complex soft tissue injury. In addition, the wealth of knowledge relating to rates of recovery from the various soft tissue injuries means that when it is applied to cases requiring an evaluation of quantum and likelihood of recovery, the lawyer receives an opinion from an expert with an understanding of the whole rehabilitation process.

Client history:

Any comprehensive account of the background to an injury (particularly where it is work-related) should include information about the claimant’s regular daily activities, whether in a work environment or home situation. A physiotherapist is accustomed to observing and assessing the impact of a client’s environment on his or her injury. This is an essential consideration when seeking to restore full function.

Case Example:

Mr T had been using an improvised workstation and subsequently incurred severe soft tissue injuries. The physiotherapist identified how the postural stresses on the body had resulted in the patient’s symptoms. Excruciating pain along the spine – relieved only by lying flat – and severe pain and tenderness of the forearms were the consequence of sitting for 3 months of intensive work on a laptop.

Client Examination:

Soft tissue injuries are difficult to assess accurately, with x-rays and scans rarely providing useful evidence. Even nerve conduction tests are of little value when assessing damage to nerves subjected to excessive stress. What is required is an evaluation of any adverse mechanical tension within the nervous system which may be restricting movement.
Physiotherapists are used to palpating and testing specific structures within the body to diagnose exactly what has been damaged, i.e. whether it is a tendon, a tendon sheath, muscle, fascia, a nerve or any combination of these. A physiotherapist can help in differentiating between whether the client’s condition is constitutional and has been aggravated by work or trauma, or is caused by work or trauma.

There is a growing acknowledgement of the need for a biopsychosocial assessment when examining people, and this is the approach traditionally taken by a physiotherapist. Social history and status, mental and emotional states, as well as working situation and lifestyle, can all contribute to how the patient reacts to and copes with symptoms.

There are many standard tests that can help with the assessment of the physical condition. One such example is the straight leg raise. The test involves the patient lying comfortably relaxed on his back. The examiner places one hand under the Achilles tendon and the other above the knee. The leg is lifted perpendicular to the bed, with the hand above the knee preventing any knee bend. The leg should be lifted as a solid lever moving at a fixed point in the hip joint.

This is a simple biomechanical test that has been recognised for hundreds of years as a way of identifying lumbar spine (lower back) problems. However, it is of limited value only. When the leg is lifted in the manner described, many structures move – the hamstring muscles, the lumbar spine, the hip and sacro-iliac joints and fascia, as well as the nerves. Pathology of any of these structures may affect the client’s reaction to the test.

An experienced physiotherapist will combine such tests with detailed palpation and observation of functional movements to arrive at the all-important specific diagnosis. In addition, the patient’s posture and manner of movement will be analysed and the results added to the overall assessment.

Case example:

Mrs B was secretly videoed by an insurance company while shopping. A physiotherapist was able to identify how the client had become so used to coping with her injuries that she avoided a lot of the normal, potentially painful, actions employed by other women shopping, e.g. standing upright with arms by her side most of the time, avoiding heavy or bulky items, loading carrier bags lightly, and using both hands to carry each bag.

Expert opinion:

An experienced clinical physiotherapist possesses an unrivalled knowledge and comprehension of how the body works under normal conditions and when coping with a disability or soft tissue injury. With regular and prolonged experience of treating soft tissue injuries, a physiotherapist can offer a valuable and meaningful opinion about all aspects of treatment and recovery.

Prognosis:

An essential component of any medico-legal report is a prediction of future developments on a balance of probabilities basis. A clinical physiotherapist sees large numbers of similar injuries from first contact through to recovery, and can thus give a reasoned prognosis based on experience. This should include the likelihood and anticipated timing of resolution, the need for further treatment and any possible long-term disability.

Conclusion:

When a lawyer is trying to find an expert witness that can help with soft issue PI cases it is worth considering an experienced physiotherapist can bring a unique and valuable perspective in any personal injury case involving a soft tissue injury. Experience of patients from first injury right through to recovery gives such specialists the widest professional knowledge when it comes to assessing future treatment and costs thereof, and arming the lawyer with the necessary detail to fully assess quantum.

Construction Dispute Resolution Expert Witness Assistance

The construction of a new home or office building can be a daunting task to manage. From the beginning of the process, stress immediately sets in. The finding and selection of a contractor is not an easy task. In fact, the pre-construction part of the project can often be the most stressful part of the project.

However, if you have ever had to go through the process of having something go wrong with the project, and the subsequent legal action, then you know pre-construction stress is nothing compared to the stress of the possibility of needing construction dispute resolution.

The Legal Aspect of Contract Disputes

When you are in the legal realm of construction dispute resolution you will likely have to rely on a construction expert witness. If you are bringing legal action against the builder you will need to prove that the builder, or builders, breached their contractual obligation. In the area of construction there are often many gray areas that a homeowner or a business owner might not be fully aware of.

These gray areas typically involve things like disclosure of building practices and codes, the pulling of city or town required permits, and various kinds of hold-harmless agreements. The legalese involved in most construction contracts should signal to buyer that he or she ought to seek legal advice before entering into any agreements.

Getting an Expert for Your Case

Most people who are engaging a construction company for work are not experts in construction themselves. Therefore, when something goes wrong with the structure of the building or elements of the structure (like electrical work, mold issues, and settling issues) it is hard for the buyer to know who is legally liable. This is when a construction expert witness is helpful.

You can hire a construction expert to come in and review the contracts and workmanship. When it comes time for trial you can call this person as a construction expert witness to bolster your case against the defendant.

If something happens to your new home or office, and really even before anything happens, you should consider bringing an expert on board to help spot any issues before the situation turns into a complex, expensive, and stressful legal process that neither side wants to deal with.

Construction dispute resolution is really a stressful process unless you have the right construction expert witness.

How To Choose A Property Expert Witness For A Valuation Report

Under the terms of Part 2 of the Landlord and Tenant Act issued in 1954, should a dispute arise over the renewal of a lease for either a commercial or business property the issue is taken into the hands of the county, and should you find yourself in this situation the aid of a property expert witness report will be invaluable to your case. The report emerges after the exchange of factual information from the two respective parties, each of which will then use the information gathered to produce a property report to argue their side of the case. Once exchanged with the rival representative on a date well in advance of the court hearing, the report will be analysed and be the central component in the court case.

The Landlord and Tenant Act of 1954 is intended to give business the additional security of tenure and under the act a tenant using property for a business of commercial act cannot merely be evicted in the procedure of providing a notice to quit or the ending of a fixed term agreement tenancy. The Act indicates quite clearly that in the case of a property owner wishing to seek the end of a tenancy that a notice must be served allowing the tenant to respond and this is where the services of an expert witness may come into play. The case will, if not resolved between the parties, result in a County Court case in which property witnesses will be called upon to produce expert reports in order to fight and defend the case of the individuals or companies being represented.

If you are involved in any case or situation with disputes regarding commercial or business property then a property expert witness will be required and this can be sourced by a wide variety of means including solicitors and chartered surveyors. In return for the fee paid, the property witness will act on your behalf to compile the expert witness report to present your case. The property expert will provided you with knowledge, expertise and a wide range of relevant experience to assist you in the disputed property case. Not only will the expert provide you with their expert property witness report but they will also attend court, as per the norm, and present the evidence gathered and issue professional witness evidence.

As in any case centring on a form of dispute with two sides being presented the witness will be cross examined and the property report will be part of this. The property expert provided, for instance, by the charted surveyor will be fully prepared, trained and experienced in such a matter and present your case in a confident and convincing manner. The service may be offered under the title of valuation expert witness or a valuation expert witness report depending on the nature of the case but both function in the same nature and with the same purpose, to assist you in a victorious case.

In this respect therefore as with all legal matters the property witness or valuation witness has a obligation and duty to the court to ensure the information provided in either the valuation report or witness report is honest, reliable and bears credibility otherwise the whole case may be placed in jeopardy but using an expert witness from a reliable company, such as a chartered surveyor, should see you avoiding such problems.

Expert Witness Engineers- Expert Opinion Based on Sound Engineering Principles

As defined by the dictionary, an expert witness is a person who has acquired specialization in a subject, often technical or other fields as well, who may present expert views without having been a witness to any incidence relating to the lawsuit or criminal case. It is an exception to the principle against giving an opinion in trial only if, the expert is purely trained by evidence of his/her proficiency, training and special knowledge.

Civil engineers must utilize their education and experience to plan, intend and supervise the projects of construction site in various industries. Moreover, a civil engineer must examine, devise, plan and assist in the execution of every step of the project. He/she will verify that all official procedures are followed along with the necessary formalities. The responsibility of the project manager is to endorse that the particular design plans are followed. The design of the construction project is done with the incorporation of commonly established engineering standards and practices. A closing report may be prepared showing that how the project was actually built as compared to the plans. Moreover, an engineer can also authoritatively verify the safety measures are being followed throughout the project period. Indeed, the professionals play important role to any construction project but can also be very imperative to any legal representative that is in need of an expert witness.

When seeking for an expert witness engineers, you must seek the assistance of professional expert. In this regard, it is important to look at the experience of your expert witness, whether education or in the field. It is crucial to your case for the expert to have relevant experience. The judge or the opposing side may feel your expert is experienced and qualified or not and you should not waste your time for a non-qualified professional.  An apprentice civil engineer hasn’t acquired that level of proficiency and will probably not have handled many different project situations so far. Also, education alone is not a designation of a good expert. Experience on the job is an essential requirement for an expert witness.
