HARRISBURG — State prosecutors filed corruption charges against a retired Philadelphia judge on Thursday for allegedly using the public resources of his judicial office to run his private real-estate company.

Willis Berry Jr., 72, turned himself in to face one felony count each of theft of services and conflict of interest.

The attorney general’s office said Berry, who served as a Philadelphia common pleas judge from 1996 to 2012, used his judicial secretary and other taxpayer resources in the daily operation of his business between 1997 and 2007.

Berry will plead not guilty, said his lawyer, Samuel Stretton.

Stretton questioned why state prosecutors waited so long to bring criminal charges. He noted the state Court of Judicial Discipline considered the ethical implications of the same allegations and suspended Berry from the bench for four months without pay in 2009.

“It’s outrageous,” Stretton said. “I see no purpose for this and I think it’s wrong.”

According to the attorney general’s office, Berry’s secretary maintained records, communicated with residents and handled bank deposits and other financial details.
