263In the present case, a difference between the date when the annulment of Implementing Regulation 2017/374 takes effect and that of Decision 2017/381 would be liable to seriously jeopardise legal certainty, since both acts impose identical measures on the applicant. The effects of Decision 2017/381 must therefore be maintained as regards the applicant until the annulment of Implementing Regulation No 2017/374 takes effect.
