As with all advertising with test seals and/or test results, a reference must be provided. This should (and must) give the consumer the opportunity to check which criteria were used to arrive at the test result or award. The same applies to the “awards” “Best Product” and “Product Winner”. If the reference is not provided, this constitutes a breach of information obligations pursuant to Section 5a UWG(LG Wiesbaden, judgment of 10.10.2018 – 12 O 29/18).
