MOSCOW (Reuters) - A Swiss court will on Monday start hearing Russia's appeal against a four-year ban imposed on its athletes competing at major international events under their own flag over allegations of doctoring laboratory data.

At a four-day hearing, the Lausanne-based Court of Arbitration for Sport (CAS) could deprive Russian athletes of their flag at next year's Tokyo Olympics.
