Labor union leader John Dougherty has asked a federal judge to order a state court to reseal an FBI affidavit of probable cause related to a search of Dougherty’s home in 2006.

The state judge recently unsealed the document when she dismissed a defamation suit Dougherty, the business manager and leading figure in the International Brotherhood of Electrical Workers, Local 98, filed against The Philadelphia Inquirer over reports he was being investigated.
