European Union – Environment. Article 10a of Directive (EC) 2003/87 and Commission Decision (EU) 2011/278 should be interpreted as meaning that they did not preclude a national provision, such as that at issue in the main proceedings, which laid down, for the submission of an application for free allocation of emission allowances for the period 2013-2020, a mandatory time limit after which the applicant had no means of correcting or supplementing its application, since that time limit was not liable to render impossible in practice or excessively difficult the submission of such an application. The Court of Justice of the European Union so held in a preliminary ruling between INEOS Köln GmbH and Germany concerning the latter's refusal to allow INEOS to correct an application for free allocation of greenhouse gas emission allowances for a certain trading period.
