WASHINGTON (Reuters) - The Federal Communications Commission suffered a setback on Monday in a long-running legal battle when a federal appeals court struck down its latest effort to loosen U.S. media ownership rules.

The Republican-led FCC in 2017 voted to eliminate the 42-year-old ban on cross-ownership of a newspaper and TV station in a major market. It also voted to make it easier for media companies to buy additional TV stations in the same market, and for local stations to jointly sell advertising time and for companies to buy additional radio stations in some markets.

The court in a 2-1 decision Monday told the FCC to take up the issue again, saying the regulator “did not adequately consider the effect its sweeping rule changes will have on ownership of broadcast media by women and racial minorities.”

FCC Chairman Ajit Pai said in a statement that despite instructions from Congress to review media ownership regulations a majority of federal appeals court judges for 15 years “has taken that authority for themselves, blocking any attempt to modernize these regulations to match the obvious realities of the modern media marketplace.”

Pai added that “there is no evidence or reasoning — newspapers going out of business, broadcast radio struggling, broadcast TV facing stiffer competition than ever — that will persuade them to change their minds.”

The FCC plans to challenge the decision, he added.

FCC Commissioner Jessica Rosenworcel, a Democrat, said “over my objection, the FCC has been busy dismantling the values embedded in its ownership policies.” She said the “court rightly sent the FCC’s handiwork back to the agency because the FCC’s analysis was so ‘insubstantial.’”

Judge Anthony Scirica, who dissented from the opinion, said “Rapid technological change had left the framework regulating media ownership ill-suited to the marketplace’s needs. The public interest analysis at the heart of the FCC’s ownership rules is as dynamic as the media landscape.”

Big media companies including Tegna Inc, CBS Corp and Nexstar Media Group Inc cited the 2017 rule change as motivation for considering expansion opportunities.

The FCC is weighing other changes to U.S. media ownership rules. In December, it sought comments on a rule that bars one company from owning two TV stations in the same market except under certain circumstances. The FCC asked if those rules continue “to serve the public interest and remains necessary.”

The FCC is also considering if existing rules that limit the number of local radio stations in a single market should be rescinded, asking if the rule “remains necessary to promote competition, localism, or viewpoint diversity.”

Free Press, an advocacy, group, said the ruling “marks the fourth time this court has rejected the relentless attempts from the FCC and the broadcast industry to weaken media-ownership limits.”
