Tesco Poland published a camcorder advertising leaflet in 2006. Consumers were informed that some models available in Tesco stores had colour viewfinders which in reality turned out to be black-and-white. The Office of Competition and Consumer Protection started a proceeding against Tesco Poland. The company issued a statement conceding that it did a mistake but that this mistake resulted from false information sent by a producer of the equipment. Tesco's legal advisers also declared that well-informed consumer would not be misled by such promotional material. However, the Competition and Consumer Protection Court in Warsaw ruled that, according to Polish regulations, violation of rules of "due care" is a sufficient factor to determine liability for the delict of unfair competition.
