Today a federal appeals court revived lawsuits brought by conservative groups against the IRS for discrimination in the processing of the tax-exempt applications.  

"A federal appeals court slapped the IRS with yet another rebuke Friday, ruling that it did, in fact, discriminate against tea party groups and insisting the tax agency prove that it’s permanently stopped the unconstitutional targeting of groups because of their political leanings.

The U.S. Court of Appeals for the D.C. Circuit said tea party groups can’t sue individual IRS employees such as former senior executive Lois G. Lerner, but said the tax agency itself has not sufficiently proved that it has banned any future targeting. The three-judge panel sent the case back to a lower court for a more thorough ruling." - The Washington Times
