Chain Of Custody Definition

1421 Words6 Pages

Chain of custody (CoC), in legal contexts, refers to the chronological documentation or paper trail that records the sequence of custody, control, transfer, analysis, and disposition of physical or electronic evidence.
One of the most important aspects of authentication is maintaining and documenting the chain of custody (a.k.a. continuity of possession) of evidence. Each person who handled evidence may be required to testify that the evidence presented in court is the same as when it was processed during the investigation. Although it may not be necessary to produce at the trial every individual who handled the evidence, it is best to keep the number to a minimum and maintain documentation to demonstrate that digital evidence has not been …show more content…

Chain-of-custody describes a process as testified to by an individual who offers real evidence in a court of law and can account for the evidence from the moment it reached his/her custody until it is offered as evidence in court.
A chain of custody provides a link between the evidence and the scene of a crime. Chain of Custody can be broadly defined as a system or way to provide a link between the evidence at the scene of the crime and till it was presented as an evidence in the court. The chain of custody must ensure that collected evidence can be accepted as truthful by the court.
The chain of custody information is important to a forensic examiner. It can help show where the evidence came from, who created it, and the type of equipment that was used to capture the evidence. This information is useful as it will help the examiner to create another copy of the evidence they can do it using the same equipment or similar process and compare it with the evidence to confirm the …show more content…

Because evidence can be used in court to convict persons of crimes, it must be handled in a scrupulously careful manner to avoid later allegations of tampering or misconduct. It is important to not only document what is being obtained, but who is doing the collection, when it was collected, and other details that validate the evidence. The chain of custody documentation provides information regarding the collection, transportation, storage, and general handling of the electronic

    The reliability and admissibility of evidence becomes a foundation to this truth as any evidence presented cannot contain elements which can provide doubt towards the validity of the prosecution. This can be shown through guideline 14 of the Office of the Director of Public Prosecutions agreement to provide advice for the NSW police towards the legal limitations or consequences of evidence obtained during the course of an investigation (Office of the Director of Public Prosecutions n.d). Identification evidence in particular has a lower weight and strength for admission to a court due to the fallibility and circumstantial nature of witnesses. The admissibility of identification evidence was previously determined by judges based on its quality with case law such as R v. Christie providing principles for discretionary powers for admissibility and Alexander v. R providing methods satisfactory to the court for identification such as identification parades under common law. (R v. Christie 1914; Alexander v. R 1981).

Iowa, 1988). The state prosecutor made a motion, at the trail of Coy, to allow the two girls to testify behind a screen or by using a closed-circuit television, to avoid further traumatizing the thirteen-year-olds (Coy v. Iowa, 1988). Before this case, “ The Iowa legislature’s purpose was to assure the fair and compassionate treatment of victims and to protect them from intimidation and future injury. Iowa stature allowed for a child to testify via closed-circuit television or by videotape” (Thuet, 1994, p.11). Therefore, because of Iowa’s statutory procedure,
