MOSCOW — Already spurned by Britain, the Russian oligarch Roman Abramovich has suffered another blow in his search for residency in Western Europe, this time with a court ruling in Switzerland.

The decision, handed down on Monday by a federal court in Lausanne, lifted a ban on the publication of a Swiss police report declaring him a threat to security. It ended a seven-month legal battle by Abramovich, a Russian billionaire, to prevent news media outlets from publishing confidential police information that led the Swiss authorities to reject his application for residency near a ski resort.

Like many Russian billionaires, Mr. Abramovich has long sought a secure shelter for himself and his money outside his home country, even though he has had no public quarrels with President Vladimir V. Putin of Russia.

For years he had an investor visa to Britain, where he owns a string of properties and the Chelsea soccer club, but he ran into trouble renewing the visa this year.
