M.R. Evid. 609

(a) In general. Evidence of a criminal conviction offered to impeach a

witness’s character for truthfulness must be admitted if its probative

value outweighs its prejudicial effect on a criminal defendant or on any

party in a civil action if the criminal conviction is:

(1) For a crime that, in the convicting jurisdiction, was punishable by

death or by imprisonment for more than one year; or

(2) For any crime if the court can reasonably determine that

establishing the elements of the crime required proving—or the

witness admitting—a dishonest act or false statement.

(b) Time limit. Evidence of a conviction is admissible under this rule only if:

(1) Less than 15 years has passed since the conviction; or

(2) Less than 10 years has passed since the witness was released from

confinement for the conviction.

(c) Effect of a pardon, annulment, or certificate of rehabilitation.

Evidence of a conviction is not admissible if the conviction has been the

subject of a pardon, annulment, certificate of rehabilitation, or other

equivalent procedure.

(d) Juvenile adjudications. Evidence of a juvenile adjudication in a public

proceeding is admissible under this rule. Evidence of a juvenile

adjudication in a proceeding that was closed to the public is admissible

only in juvenile proceedings that are also closed to the public.
