Convicted last month of racketeering and honest services fraud, Former Luzerne County Common Pleas Court Judge Mark A. Ciavarella has filed a series of motions to have the most serious charges against him tossed.

Three separate documents filed by Ciavarella’s attorneys Friday challenged the sufficiency of evidence presented by federal prosecutors and rulings made by the judge who oversaw the seven days of trial and two days of jury deliberations. In them, Ciavarella asks for an arrest of judgment, acquittal or new trial on seven of his 12 convictions.
