Legal experts said Friday that the lawsuit filed by the New York State Association of Criminal Defense Lawyers against the judges of the New York State Court of Appeals over rates paid to lawyers in death penalty cases has created an unprecedented situation that raises a host of difficult questions.

Albany Law School Professor David Siegel, the dean of New York procedure experts, and Arthur Karger, the author of a treatise on the Court of Appeals, both said they were unaware of any situation where the Court has had to grapple with its ability to pass upon its own administrative order.
