M.R. Evid. 508

(a) Privilege. If the federal or Maine constitution, or a federal or Maine

statute, creates a governmental privilege, a person may claim the

privilege pursuant to the applicable provision of law. There is no other

governmental privilege.

(b) Effect of sustaining a claim of governmental privilege. If the court

sustains a claim of governmental privilege and thereby appears to

deprive another party of material evidence, the court must make any

orders required by the interests of justice. These orders may include:

(1) Striking the testimony of a witness;

(2) Declaring a mistrial;

(3) Making a finding on an issue as to which the evidence was relevant;

or

(4) Dismissing the action.
