WASHINGTON — Twice in recent years, the Supreme Court rebuked the federal appeals court in Atlanta for its rigid attitude toward filing deadlines in capital cases. The appeals court does not seem to be listening.

A few days after Christmas, a divided three-judge panel of the court ruled that Ronald B. Smith, a death row inmate in Alabama, could not pursue a challenge to his conviction and sentence because he had not “properly filed” a document by a certain deadline.

As it happens, there is no dispute that the document was filed on time. But it was not “properly filed,” the majority said, because Mr. Smith’s lawyer did not at the same time pay the $154 filing fee or file a motion to establish something also not in dispute — that his client was indigent.

Nor did the majority place much weight on the fact that the lawyer himself was on probation for public intoxication and was addicted to crystal methamphetamine while he was being less than punctilious. In the months that followed, the lawyer would be charged with drug possession, declare bankruptcy and commit suicide.
