Mikhail Khodorkovsky, once Russia's richest man, is now one of Russia's best-known political prisoners... Mr. Khodorkovsky has languished in a Siberian prison camp since 2005, and Russian authorities want to keep him there. With a diminished but nevertheless sizable fortune, not to mention moral capital because of his refusal to bend to Kremlin pressure, the former oil baron might still hope to have some influence after his release, particularly if he is freed before the uncertain 2008 presidential contest. That is one likely reason that he and a business associate face additional charges -- just months before they would be eligible for parole. If convicted, he would have to wait out the next presidential election and a lot more.

The charges are magnificently implausible. Mr. Khodorkovsky is alleged to have embezzled and then laundered $32 billion through affiliates of his oil company, Yukos. Inconveniently for the government, PricewaterhouseCoopers was vouching for Yukos's books throughout the period in question.

More convenient for the Kremlin, the auditor last month suddenly disowned and withdrew a decade's worth of Yukos audits, helping to neuter Mr. Khodorkovsky's defense. Before the announcement, the firm had insisted that its work was sound. After the announcement -- surprise, surprise -- a Moscow court ordered new hearings on a $9 million tax case against PricewaterhouseCoopers that, until then, had not been going the company's way.

A spokesman for PricewaterhouseCoopers insisted that its decision to withdraw the audits had nothing to do with the months of harassment it received from Russian authorities -- including a police raid, the tax lawsuit and threats that its license to operate in Russia could be revoked. At the same time, the company declined to publicly detail its reasons for withdrawing the audits...
