LONDON, Nov 13 (Reuters) - Apple ( AAPL ) was on

Thursday refused permission to appeal against a London tribunal

ruling that it abused its dominant position by charging app

developers unfair commissions.

The Competition Appeal Tribunal (CAT) ruled against Apple ( AAPL )

last month after a trial, finding Apple ( AAPL ) had abused its dominant

position by shutting out competition in the app distribution

market and "charging excessive and unfair prices" as commission.

Apple ( AAPL ) - which has faced mounting pressure from regulators in

the U.S. and Europe over the fees it charges developers - has

previously said the ruling "takes a flawed view of the thriving

and competitive app economy".

The CAT refused Apple ( AAPL ) permission to challenge its ruling at

the Court of Appeal, but the company can still apply directly to

the court.
