SMS Text Messages - Hearsay Evidence

SMS Text Messages - Hearsay Evidence
.
C2247 / R v Leonard 2009
YEAR OF CASE: 2009
CITATION: [2009] EWCA Crim 1251
COURT: Court of Appeal
.
SUMMARY:
Large quantities of various types of Class A drugs and cash were found in L's bedsit and on his person during a search by police.
.
At trial for possession of class A drugs with intent to supply, the prosecution argued that L was a street dealer and those drugs found had been his 'stock pile'. The defence argued that the drugs were for his personal use and that he was not a dealer but he had the large amount that was found because he intended to share them with his girlfriend.
.
The prosecution wished to admit two text messages as evidence to support its case. Both were from different people, one to compliment the 'gear', the other to complain about it. The defence argued that the text messages were inadmissible hearsay. The judge rejected the argument and admitted them as evidence of bad character as opposed to hearsay.
.
L was convicted and appealed arguing that the judge had been wrong in law.
.
Held:
Appeal dismissed. Convictions upheld. The text messages were hearsay evidence and not evidence of bad character. They fell in the scope of section 114 and 115 of the Criminal Justice Act 2003 and had to for the following reasons;
.
(i) they had not been made in oral evidence,
(ii) they were statements of fact or opinion within the meaning of section 115(2) of the 2003 Act,
(iii) the reason for the evidence being admitted was to establish the matters stated in the texts to try to prove that L had supplied the drugs to the senders of the texts, and
(iv) each message was designed to make the person in receipt of them believe the matters stated in them as required by section 115(3).
.
Once it is established that the texts are hearsay they then fall to be analysed as to whether they meet the statutory requirements regarding admission. The only basis upon which they could be admitted would be under section 114(1)(d); that it was in the interests of justice to do so. To ascertain whether that is the case, regard must then be had to the 9 propositions in section 114(2) and as they fail to meet some or all of those criteria, they may be hearsay, but they are inadmissible hearsay evidence. Despite this there was still a very strong case against L without them and their admission had not tainted the rest of the trial.
.
Note:
In this instance the senders of the text messages were never identified. If the authors can be identified then the text messages may become admissible where the authors can be potential witnesses. Thus allowing the evidence to be tested by way of cross-examination with any requisite measures in place, for example special measures under the Youth Justice and Criminal Evidence Act 1999 to alleviate such issues as fear.

Ultra-thin membrane changes (U)SIM card usage

Ultra-thin membrane changes SIM card usage

Examiners may come across an ultra-thin (0.3mm) membrane that lays over the contacts of a SIM card. Called the V200 SIM Dialer, the membrane is "Prefix base programmable (For routing prefix and bypass prefix setting)". What does that mean? Well, it allows mobile phones installed with SIM Tool Kit menu (most up to date phones have them) and define access to the network. The point being, if you are looking for least-cost routing for calls or want to use a calling card, rather than have mobile network call charges, then this device makes that happen, apparently.

How does it do it? "Dial the desired number directly each time you call, SIM dialer V200 will automatically dial IP access in front of the dialed number".
As the manufacturer promotes, using their device will not change your dialling habits and there is "No cutting, No pounching your SIM".

As the device has been programmed, and looking at the on-board chip, there should be a reader for it or one could be constructed. This throws me back to the old days of ponyprog and PIC basics. Of course, of equal importance is how does this device impact when examining the handset and SIM card? Will manual examination be the only course for examination or do the current handset and SIM readers detect changes this device makes to them? What evidence is there for call history or data usage? These are just a few of the questions to get examiners started.


It seems this programmable ultra-thin membrane is not limited to just SIM calls, but there is a USIM version (U-SIM V33G) that can be used to unlock iPhones. There is a video that is useful to watch so that examiners can at least comprehend how ultra-thin the membrane is and how it is installed:-

Mobile Telephone Evidence - TIPS

Mobile Telephone Evidence - TIPS

Vinny Parmar sent in a couple of handset examination tips for my webblog readers. Thanks Vinny..

1. Nokia 6280 Series 40
- Handset can be powered on without the need for a SIM card. Access granted to menu's & data areas. Call log is not available. Contact list only viewable if Contact settings memory allocation changed to Phone Memory only. All other data areas accessible

2. Samsung D600:
- Memory card can be password protected via GUI. However once card removed from handset card is no longer protected - Requires further testing to confirm on all firmware versions and other models.

Article on SIM Card Readers

Deleted SMS text messages

Deleted SMS text messages

GSM 11.11 (ETSI TS 100 977) is a Standard containing mandatory and optional requirements relevant to Subscriber Identity Module (SIM) cards. An optional service that an Operator may provide to a subscriber of its services is Short Message Service (SMS) text messaging. The requirements relating to storing sent and received SMS text messages, in the user memory area of the SIM card, are identified at GSM 11.11 cl10.5.3. When a message that is received and is subsequently deleted by the user of the SIM, the user can no longer gain access to that data. The details about a particular SMS message that has been deleted are removed from the SIM's memory table thus the mobile telephone will no longer display the SIM details of that message to the user.

Although the details of the SMS text message are no longer accessible by the user, GSM 11.11 makes it clear the physical data relating to the entire text message may still be recorded on the card. GSM 11.11 procedure for "Erasure" of text messages states:

GSM 11.11 cl 11.5.2
"Erasure: The ME will select in the SIM the message area to be erased. Depending on the MMI, the message may be read before the area is marked as "free". After performing the updating procedure with EFSMS, the memory allocated to this short message in the SIM is made available for a new incoming message. The memory of the SIM may still contain the old message until a new message is stored in this area."

Using specialist examination tools it is therefore possible to recover erased (deleted) SMS text messages from a SIM card. Where a previously deleted message has been over-written by either new data allocated to the memory area previously occupied by the deleted data or the handset automatically over-writes as a function of its operating procedure (usually over-writes with 000000's) the erased (deleted) data in the SIM are no longer recoverable. Hopefully this
information will assist if you are asked is it possible can deleted text messages be recovered, and, if not recoverable, why not?

Mobile Telephone Evidence

Code and Data go hand in hand

Examiners are familiar with the fact that from time to time found appended to SMS text messages there appears unintelligible code that cannot be read in context with the user's message itself. Such code as @@@ or /./@@ and so on may raise the notion that the SIM reader has not decoded the message correctly. On the contrary, the SIM reader is most likely to have done its job. The assignment of code being added to the data is so that the mobile telephone knows what to do with a message next time it reads it. The cause behind this is fairly straightforward. Phase 2+ handsets (GSM Release 98 onwards) adopted UCS2 (Universal Character Set 2) that allowed highlights to be added to or with data. For instance, italics or colours and so on. Most GSM SIMs' are programmed with GSM Default Alphabet and not UCS2. To corroborate finding code with data, following a SIM read, may require viewing the message through the handset.

Mobile Telephone Evidence

For those of you who have attended the TrewMTE GSM Mobile Telephone SIM forensic Card training courses will know the user content elementary file (EF LND) Last Number Dialled. We know from the GSM SIM Standard that this EF is optional, but once allocated and activated in SIM, has a number of mandatory features. The EF stores the number dialled by the user. In the words of the academic authors Redl, Weber & Oliphant "The last number dialed (EFLND) contains a list of the last numbers that were dialed using the SIM." Historically, the numbers found in EFLND have consistently shown to have been stored following selection of numbers from other EFs in the SIM and not numbers dialled on the handset keys or from a handset's phonebook. It has been noted recently that certain SonyEricsson handsets that have dialled numbers are being recorded into this particular elementary file (EFLND). I thought this info was worth passing on - to avoid or reduce confusion during examination.
