62Having regard to the fact that the check carried out by ECHA following a first decision requiring the registrant to bring the dossier into compliance, is merely the continuation of the same, single procedure, it must be held that, if the registrant completely fails to provide the information requested, no new assessment of the compliance of the dossier and therefore no new decision within the meaning of Article 42(1) of Regulation No 1907/2006 is required. On the other hand, where, in response to the decision requiring the registration dossier to be rendered compliant, the registrant avails itself of the possibility, laid down in Annex XI of Regulation No 1907/2006, of adapting the standard testing regime and the submissions in that regard are not manifestly unreasonable, having regard to the requirements of that annex, and do not therefore amount to an abuse of procedure, it must be held that, as Annex XI provides, ECHA is to assess those adaptations. It also follows from the foregoing that the evaluation in question is to be made pursuant to Article 42(1) of Regulation No 1907/2006, which refers to Article 41 of the same regulation as regards the decision-making procedure.
