PHILADELPHIA (AP) - The status of Libertarian Party candidates on the Pennsylvania ballot remains uncertain as a court hearing stretched into another day.

Lawyers for the party and for challengers supported by the state Republican Party sparred Tuesday over a few dozen signatures that could put the Libertarians over the 20,601 signatures they need.

Commonwealth Court Senior Judge James Gardner Colins did not immediately rule on those motions and extended the hearing into Wednesday.

Meanwhile, the lawyers resumed their review of the last few hundred signatures - a process that could give the Libertarians the signatures they need regardless of how the judge rules.

The Libertarian candidates for president, U.S. Senate and the three state row offices are currently on the Nov. 6 ballot.
