Thanks to Chuck Berry, concert-goers in Finland can now receive actual compensation for poor concerts - the first decision of its kind. The ruling stems from a 2013 concert by the rock and roll legend in Helsinki. A very apologetic Berry confirmed to the crowd that he was sick, explaining the show's sub-par performance level. Two years later, the Finnish Consumer Disputes Board ruled that attendees were allotted a 50 percent refund of the original ticket purchase.

The subject of concert refunds in Finland isn't a grey area, as one might suspect. Despite the highly-subjective nature of a "good" concert, Board chairman Paul Stahlberg informed Finnish broadcast Yle that certain degrees must be pertinent. For one, an artist(s) can be sick - as Berry was - and the show can be deemed refundable. However, sobriety isn't. "It's not at all unusual at rock festivals that some artists are high, and that doesn't even necessarily affect the quality of their performances," he says.

"Anyone seeking a ruling like this is always spurred by a subjective opinion, but that's not enough to get a refund," Stahlberg continues. "What is significant is a generally agreed view that the concert was a failure, as it was in the Chuck Berry case."

Festivals, however, are even trickier, considering the price of admission isn't simply for one specific artist. "There are numerous different performers at a festival and so it have to be evaluated as a whole. Even the marching order affects perception of the overall quality. A failed performance by a featured star is a bigger deal for consumers than one by a warm-up band," Pauli Ståhlberg explains.

The effectiveness and success of the ruling is to be determined. Whether other countries will follow suit remains to be seen.
