Appellate Law

As a former judicial appeal clerk and judicial staff attorney, David Lewarchik has an invaluable perspective.  Unlike most appellate attorneys, he has seen how judges make their decision because he worked with them to help them make the decisions.  This perspective provides an invaluable advantage to his clients.

State Post-Conviction Law & Habeas Corpus Law

Collateral attacks to a conviction, in the form of a Habeas Corpus Petition or Post Conviction Petition, may provide a valuable means to attack a trial court judgment when a direct appeal is not available.


“I have worked with David Lewarchik and have known him a long time. He is a skilled appeal lawyer and writes great legal briefs.”

-Anthony Longo, Esq. – Partner at Brennan Garvey
