“ But an unaccepted offer of new counsel can hardly render harmless any error in dismissing an already appointed attorney.
Lawyers are not necessarily fungible goods, to be replaced at the whim of the court. Counsel's prior experience in a case, his familiarity with the facts and prior proceedings, and the position of trust he may have gained with the defendant are factors arguing for continued representation by the same attorney. This case is barren of any indication that the interests of petitioner were considered in the dismissal of his appointed counsel. ”
