A Russian court has ordered a retrial of a case against a rural head teacher accused of using pirated Microsoft software in his school.
Last month a lower court in Perm, some 1,000km (620 miles) east of Moscow, dismissed the case as "trivial".
But a higher court has ruled it should proceed against Alexander Ponosov after pressure from the prosecution.
The trial has been seen as a response to international pressure to crack down on piracy in Russia.
Industry experts say Russia ranks second only to China in use of illegal computer software and bootlegged music.
