In all cases, the defendant may waive the right to testify. The judge shall ascertain from the defendant whether the waiver is a knowing, voluntary and intelligent waiver. A waiver colloquy, on the record, should be conducted by defense counsel, but may be supplemented by the Court and/or the Attorney for the Commonwealth. In a jury trial, the colloquy shall be held outside the presence of the jury before the defense rests its case.
