The Guam Rules of Evidence govern how to collect, present and apply evidence in proceedings in Guam courts. These Rules of Evidence generally apply to civil actions and proceedings, to criminal cases and proceedings and to contempt proceedings except those in which the court may act summarily. With respect to privileges the rules apply at all stages of all actions, cases, and proceedings.
However, the rules (other than those with respect to privileges) do not apply in the following situations:
- During determination of questions of fact preliminary to admissibility of evidence when the issue is to be determined by the court.
- Proceedings before grand juries.
- During miscellaneous Proceedings such as for extradition or rendition; detention hearing in criminal cases; sentencing, granting or revoking probation; issuance of warrants for arrest, criminal summonses, and search warrants; and proceedings with respect to release on bail or otherwise.
Guam Rules of Evidence are construed to secure fairness in administration and elimination of unjustifiable expense and delay. In addition, the rules aim at promotion of growth and development of the law of evidence for ascertaining truth and justly determining proceedings.
