A New York lawyer was disbarred on Thursday after he admitted, as part of a guilty plea to obstruction and perjury charges, to creating phony evidence to help a business owner friend bolster a multimillion-dollar claim of damages in a breach of contract case.

The New York Supreme Court Appellate Division, First Department, ordered the disbarment in a disciplinary ruling against Joel Zweig, who was admitted to practice law in New York in 1991. Zweig in September entered a guilty plea in San Francisco federal court to criminal charges of obstruction of justice and perjury. The First Department wrote that, in light of his conviction on those charges, disbarring him was the proper disciplinary sanction.
