Jan 13 (Reuters) - The U.S. Supreme Court declined on

Monday to hear a bid by Meta Platforms ( META ) to avoid a

multi-billion dollar class action by advertisers that accused

the Facebook and Instagram parent company of overcharging them

by inflating the number of people their ads might reach.

The justices turned away Meta's appeal of a lower court's

decision that let advertisers seek damages as a group over

Meta's claims about the "potential reach" of their ads.
