Instead, Ikea rented diesel generators large enough to power a shopping mall . The engines roared to life in a loud rebuke to the corrupt executives who thought they had the retailer cornered, and soon the utility turned on the power .

As Ikea opened markets across Russia, and became one of the most outspoken Western corporate critics of Russian corruption , renting generators to thwart removing from power companies became standard practice.

Ikea said that such a deception could cost it about $196 million over two years.

Ikea canceled the contract and sought redress in Russian local court. But in rulings over the last two weeks, Ikea has lost another 5 million euros in damages that the judges awarded the generator rental firm for breach of contract .

Ikea disclosed the details of its loss to The New York Times last month, saying that it hoped publicity might compel the Russian authorities to investigate.

“We have encountered something here that is outside the scope of what we normally encounter,” Mr. Thordson said, describing the universal retailer’s situation in Russia. “I have never experienced anything like this.”

The leader of the engine rental company and the former Ikea employee accused of accepting bribes denied any wrongdoing.
