The FCC just can’t seem to catch a break these days. Chairman Tom Wheeler has already been inundated with complaints over the agency’s net neutrality policies, and now he’s facing a hefty lawsuit from the National Association of Broadcasters. In particular this group of television companies is taking issue with recent FCC policies aimed at curbing industry monopolization.

In particular NAB’s lawsuit addresses the FCC Media Bureau’s recent policies governing “joint sales agreements” in the television industry, which were enacted in March. The policies place scrutiny on broadcasting companies that share resources, such as advertising staff, claiming these business deals are being made to circumvent FCC rules baring a single company from owning more than one of the top four stations in a region.

The FCC’s guidelines are designed to prevent huge media companies from controlling all of the content in a region, and to ensure that a diverse array of views and opinions are presented on the airwaves.

NAB is arguing in their law suit that the policies are “arbitrary, capricious and an abuse of discretion,” claiming that they will have an adverse effect on smaller companies that need to share resources to cut costs.

This policy “abandons longstanding precedent” and “adversely affects NAB and the member broadcasters whose interest it represents by rendering previously legitimate transactions presumptively invalid,” the group wrote in their legal filing.
