PITTSBURGH — The Superior Court today rejected Republican state Sen. Jane Orie’s claim that it would be double jeopardy to retry her in October on charges that she misused her state-funded staff to do campaign work.

It was the second legal setback for the Pittsburgh-area lawmaker this week.

On Monday, Allegheny County prosecutors charged Orie with perjury, forgery, evidence tampering and obstruction of justice in connection with her testimony and some documents she used to defend herself at trial earlier this year, including two documents that led to a mistrial on the original corruption charges in March.

That’s when Allegheny County Judge Jeffrey Manning aborted the trial during jury deliberations, after agreeing with county prosecutors that two documents used to undercut the key prosecution witness, Orie’s former chief of staff Jamie Pavlot, contained a “cut-and-paste” of Pavlot’s signature.

Orie, 49, of McCandless, who covers southern Butler County, appealed, claiming a new trial was unfair. She said prosecutors raised the forgery issue because they feared the jury was about to acquit her on the original corruption charges.
