Dyson won a five-year legal battle to overturn European standards on energy labeling of vacuum cleaners in a decisive victory for the company's founder and well-known Brexiter Sir James Dyson.
A court in Luxembourg on Thursday said it would support the request from the group of engineers that the system would have deceived consumers and discriminated against its technology and would have canceled the regulation.
In its ruling, the Court of the European Union stated that "the tests of the energy efficiency of a vacuum cleaner carried out with an empty vessel do not reflect the conditions as close as possible to the actual conditions of use". The label will remain in place for a minimum of two months and 10 days to allow for appeal time.
The group said the decision is "a victory for consumers across Europe".
John Doherty, a Penningtons Manches law firm, said it was a significant victory for Dyson. "It is not unprecedented, but it is quite rare that a part of the primary law of the EU be canceled".
All household vacuum cleaners sold in the EU must have energy labels to enable consumers to judge which models are most efficient. The system is mainly based on energy consumption, but includes factors such as dust emissions from exhaust and noise from the machine.
Dyson, famous for its cleaners without bags, argued that the EU laboratory tests that determine the labeling ratings for vacuum cleaners do not reflect real use, because the machines are not loaded with dust in advance.
The company claimed that since vacuum cleaners with bags and filters clogged over time, often causing a loss of suction, this unjustly discriminated against cyclone technology in Dyson bagless machines, which, he said, achieved consistently high performance. The result, Dyson said, is that a car with a high score could see its performance fall as it is used at home and fills up with dust.
The British home appliance brand also claimed that the regulations created loopholes exploited by rival manufacturers. He claimed that some competing machines used low engine power during the test state, only to use electronic sensors to increase the use of energy when they were filled with dust. Sir James compared this alleged behavior to the Volkswagen diesel emissions scandal.
The judgment represents a significant victory for Sir James, who was once so favorable to the European Union that he pushed for the United Kingdom to enter the single currency, but has since fallen for the block's love and became a supporter of Brexit.
It is also a major turning point compared to a few years ago, when Dyson lost in a previous hearing, but then appealed to the European Court of Justice. Last May, the court referred the case to the court of first instance for a reconsideration after discovering that it had "distorted the facts", ignored its own law and Dyson's evidence and did not provide explanations.
"The legal process has been long, distracting and costly, with the odds that they are building up against us." Most companies simply do not have the resources to fight the regulations of this nature, it is terrifying that this illegal and fundamentally anti-competitive behavior is has been approved for so long ", added the Dyson Group on Thursday.
BSH Hausgeraete, which manages the German home appliance brands Siemens and Bosch, said that it will "carefully analyze the decision and what it will mean for the manufacturers of vacuum cleaners".
"It will be particularly interesting to see the effect that the decision will have on consumers.We believe in the purpose of the energy label to provide clear guidance and information for consumers.We can not wait for the European Commission to take the appropriate measures to provide even better information ".
