WASHINGTON, Oct 6 (Reuters) - The U.S. Supreme Court

declined on Monday to halt key parts of a judge's order

requiring Alphabet's Google to make major changes to

its app store Play, as the company prepares to appeal a decision

in a lawsuit brought by "Fortnite" maker Epic Games.

The justices turned down Google's request to temporarily

freeze parts of the injunction won by Epic in its lawsuit

accusing the tech giant of monopolizing how consumers access

apps on Android devices and pay for transactions within apps.

A federal appeals court in July upheld the lower judge's

sweeping order against Google.
