Possible attorney responses to a client's intention to testify falsely are withdrawal from the case, insistence that the client testify in narrative form (avoids attorney complicity in the perjury), and disclosure to the court of the client's intention to commit perjury. All of these alternatives present ethical and legal problems. If attorneys have sufficient tools to persuade the client to testify truthfully, then neither the legal prohibitions against perjury nor the client's constitutional rights to testify or to receive effective counsel are compromised. The legal rules that govern client perjury and disclosure of client confidences should allow an attorney to threaten the client with withdrawal from the case and disclosure of the proposed perjury to the succeeding attorney. The rules should require limited disclosure to the succeeding attorney when the original attorney withdraws because the client cannot be dissuaded from committing perjury. This limited disclosure would prevent withdrawal from becoming a self-defeating formality in which the client seeks a new lawyer solely to conceal the planned perjury. Under the existing rules on attorney withdrawal, such disclosure could not occur. 64 footnotes
