D. Mass. L.R. 116.4

(a) Availability of Audio and Video Recordings

(1) The government must provide at least one copy of all audio and video recordings

in its possession that are discoverable for examination and review by the defendant

parties.

(2) If a defendant requests additional copies, the government must make arrangements

to provide or to enable that defendant to make such copies at that defendant’s

expense.

(3) If in a multidefendant case any defendant is in custody, the government must insure

that an extra copy of all audio and video recordings is available for review by the

defendant(s) in custody.

(b) Composite Recordings, Preliminary Transcripts and Final Transcripts. The parties

must make arrangements promptly to provide or make available for inspection and

copying by opposing counsel all:

(1) Composite electronic surveillance or consensual interception recordings to be used

in that party’s case-in-chief at trial, once prepared.

(2) Preliminary transcripts, once prepared. A preliminary transcript may not be used at

trial or in any hearing on a pretrial motion without the prior approval of the court

based on a finding that the preliminary transcript is accurate in material respects

and it is in the interests of the administration of justice to use it.

(3) Final transcripts, once prepared.

(4) Nothing in this rule shall be construed to require a party to prepare composite

recordings, or preliminary or final transcripts, of any recording.
