Two months ago, on behalf of Client, Lawyer argued in the State Supreme Court that a particular aspect of a state statute should be declared unconstitutional. The briefs are submitted and the Supreme Court has scheduled oral argument in two months. Lawyer is now preparing to argue in a trial court in the same jurisdiction, on behalf of New Client in a different case, that the particular aspect of the same state statute is constitutional. Both clients give informed consent in writing to the conflict.   Is Lawyer subject to discipline?
