A track record of tardiness in filing Social Security appellate briefs earned a law firm a standing, $500-a-day sanction from a federal judge for documents submitted late without good cause.

The fine, imposed by District Judge Faith Hochberg in Newark, N.J., when Rahway’s Langton & Alter filed a brief more than a month after a due date, will also apply in future cases of late briefs and court personnel will no longer call the firm with reminders.
