On March 19th, Law360 published an article by our colleagues Casie Collignon and Jennifer Benda titled “Tea Party v. IRS: Tax Trouble or Class Action Nightmare?” The article addresses growing litigation by tea party groups arising out of the alleged additional scrutiny the IRS applied to the groups’ petitions for tax-exempt status as 501(c)(4) social welfare organizations. While the press has covered these stories as being about campaign finance, the litigation raises significant class action, tax, and privacy questions that every practitioner should be following. We will continue to follow this important story here.
