Philadelphia District Attorney Seth Williams fired back Tuesday at his predecessor's legal push to remove him from office, arguing that neither she nor a state court had the authority to kick him out.

In a response to a lawsuit filed this month, the city's embattled top prosecutor accused former District Attorney Lynne M. Abraham and her co-plaintiff, lawyer Richard Sprague, of trying to circumvent the process spelled out by the state constitution for removing elected officials.

"Other than having preceded him in the elected office of district attorney and having a generalized concern about the operation of the office and a desire to see that it functions in an efficient and effective way, [Abraham] can identify no basis for private standing," Williams' attorney Thomas Burke wrote.

Of Sprague, Burke added: "He provides little more than generalized boilerplate statements of concern arising out of the fact that his clients are impacted by routine decisions of the Philadelphia District Attorney's Office."

Despite agreeing to a suspension of his law license that will take effect May 13, Williams has vowed to remain in his post — and to continue collecting his $175,572 annual salary — as he fights to clear his name in federal court.

He has appointed his top deputy, Kathleen Martin, to handle day-to-day legal decisions about the hundreds of criminal cases moving through his office and has limited himself to an administrative role.

Abraham and Sprague argued in their lawsuit that without an active law license, Williams no longer met the requirements required by state law to remain in his job.

Their suit complicated the relationship between Abraham, who served as district attorney for 19 years, and Williams, a protégé who surprised her with a 2005 bid to unseat her. Williams lost that race, but won the job four years later after Abraham decided not to seek another term.

In his response to Abraham's lawsuit Tuesday, Williams argued that a state court was not the appropriate place to address Abraham's and Sprague's concerns.

The Pennsylvania Constitution requires all elected officials convicted of felony crimes to resign upon receiving their sentences. But state law also spells out an avenue whereby private citizens can file a complaint for removal against a sitting chief prosecutor by first taking complaints to the attorney general or the disciplinary board of the state Supreme Court.

Sprague and Abraham have done neither, Burke wrote.

The state constitution also empowers the governor to remove elected officials for "reasonable cause," but only with the approval of two-thirds of the Senate. Although Gov. Wolf has called on Williams to resign, he has not indicated that he might take steps to force Williams out.

"It is clear that this court has no authority to remove a duly elected district attorney," Burke wrote.

Williams has denied allegations that he repeatedly sold the influence of his office to two wealthy benefactors who plied him with gifts that included luxury vacations, a used Jaguar convertible, and high-priced clothing and other items, including a $205 Louis Vuitton necktie and a Burberry watch.

A federal judge has scheduled his trial on charges of honest services fraud and other bribery-related counts for May 31.

Common Pleas Court Judge Abbe F. Fletman has not set a date for a hearing.
