WASHINGTON, Oct 31 (Reuters) - A three-judge appeals

court on Thursday questioned whether the U.S. Federal

Communications Commission has authority to reinstate landmark

net neutrality rules.

The FCC under President Joe Biden voted in April along party

lines to reassume regulatory oversight of broadband internet and

reinstate the rules adopted in 2015 that were rescinded under

then-President Donald Trump. The 6th U.S. Circuit Court of

Appeals in August blocked the FCC from enforcing the rules.
