Apple and Amazon have successfully fought off a mass lawsuit in Britain over alleged collusion between the tech giants to remove resellers of new Apple products from Amazon's website, a tribunal ruled on Tuesday.

Apple is accused of overcharging consumers for software sold via the App Store in a £1.5 billion class-action lawsuit bought by Rachael Kent-Aitken on behalf of 20 million UK consumers. (That equates to about $1.8 billion in US dollars.)

Lawyers representing the class action said that Apple excluded potential rivals from competing for customers on devices running its iOS operating system by forcing developers to sell their apps exclusively through its own App Store and charging commissions of 30% for purchases.
