A Philadelphia judge has denied Duane Morris’ preliminary objections in a legal malpractice case brought against the firm by a local developer who alleges the asset protection plan the firm designed for his family led to part of their money being invested in feeder funds to Ponzi-schemer Bernard Madoff.

Judge Gary S. Glazer denied the objections Thursday in a one-paragraph docket entry without any opinion explaining his decision. He gave the firm 20 days to respond to the complaint filed by Sarah and Daniel J. Keating III.
