Rule 4-343. Sentencing.
((d) Reports of Defendant’s Experts. Upon request by the State after the defendant has been found guilty of murder in the first degree, the defendant shall produce and permit the State to inspect and copy all written reports made in connection with the action by each expert the defendant expects to call as a witness at the sentencing proceeding, including the results of any physical or mental examination, scientific test, experiment, or comparison, and shall furnish to the State the substance of any such oral report or conclusion. The defendant shall provide this information to the State sufficiently in advance of Phase I of the sentencing proceeding to afford the State a reasonable opportunity to investigate the information. Upon request by the
State, the court may postpone the sentencing proceeding if the court finds that the State reasonably needs additional time to investigate the defendant’s disclosure.
