Paraphrase the following paragraph:
The implied power to adopt decisions finding an infringement in the pursuit of a legitimate interest concerning the application of competition law does not derogate in any way from the powers which Regulation No 17 confers on the Commission, but supplements them.
However, the implicit power to adopt decisions establishing an alleged offence is no different to the powers conferred on the Commission by Regulation No 17, but complementary to those conferred on it by regulation No 17, when the legitimate interest concerning the implementation of competition law is pursued.
