The U.S. Supreme Court won't review the case of the Ohio leader of a breakaway group that was accused in hair- and beard-cutting attacks on fellow Amish.

Defense lawyers challenged the constitutionality of the federal hate crimes law and how a kidnapping allegation was used to stiffen the sentence for 71-year-old Samuel Mullet Sr. He petitioned the Supreme Court after a federal court rejected his appeal last May.

Mullet's attorney, Ed Bryan, told Cleveland.com he is disappointed by the high court's decision this week not to take up the case.

Prosecutors said some of the victims in the 2011 attacks were awakened in the middle of the night and restrained as others cut their hair and beards, which have spiritual significance in the Amish faith. Prosecutors alleged the motive was religious, while the defense attributed it to family disputes.

Mullet, who led a group in the eastern Ohio community of Bergholz near the West Virginia panhandle, was accused of orchestrating the attacks. Despite arguments that he wasn't present during the hair-cuttings, he received an 11-year sentence.
