HARRISBURG — The race for an unprecedented three open seats on the Pennsylvania Supreme Court will involve a dozen candidates.

Six Republicans and six Democrats filed nomination petitions by Tuesday’s deadline to get their names on the May 19 primary ballot. The top three vote-getters in each party will compete in the Nov. 3 general election to pick the newest members of the seven-seat court.

The GOP candidates are Supreme Court Justice Correale Stevens, who was appointed to complete the term of another justice; Superior Court judges Cheryl Allen and Judy Olson; Commonwealth Court Judge Anne Covey; Adams County Judge Michael George; and Montour County District Attorney Rebecca Warren.

The Democrats are Superior Court judges Christine Donohue, Anne Lazarus and David Wecht; Philadelphia Judge Kevin Dougherty; Jefferson County Judge John Foradora; and Allegheny County Judge Dwayne Woodruff.

Republican and Democratic candidates for two open seats on the intermediate appellate courts also filed petitions Tuesday.
