Apple has filed a lawsuit against Russia's anti-monopoly regulator over alternative payment alternatives on its App Store platform, according to court documents obtained by the RIA news agency on Sunday.

In late October, Russia filed an antitrust complaint against Apple, alleging that it failed to allow app developers to inform customers about other payment choices while using its App Store. If proven guilty, Apple might face a fine depending on its revenue in Russia, according to the report.

The Moscow Arbitration Court designated Apple as a claimant and Russia's Federal Anti-monopoly Service (FAS) as a defendant in "economic conflicts over administrative legal relations" in documents published on Dec. 1.Russian man claims iPhone made him gay – files lawsuit against Apple

On Dec. 2, Apple sought that further records be submitted to the case, according to RIA. Apple did not immediately reply to a major Newswire request for comment.

According to Forbes Russia, the proceedings are related to a warning FAS issued on Aug. 30 regarding Apple's apparent failure to advise consumers that they might pay for transactions outside the App Store.

A request for comment from the FAS was not immediately returned.

In September, a federal judge in the United States announced a judgment compelling Apple to enable developers to send their users to other payment systems, causing a backlash against the company's App Store guidelines.
