See the text of the decision. (see paras 27-29) 2. See the text of the decision. (see paras 42-44) 3. Provisions which, in order to be adopted, require political choices falling within the responsibilities of the EU legislature cannot be delegated by the legislature. It follows from this that implementing measures adopted by the Commission cannot amend essential elements of basic legislation or supplement it by new essential elements. Identifying the elements of a matter which must be categorised as essential must be based on objective factors amenable to judicial review, and requires account to be taken of the characteristics and particular features of the field concerned. (see paras 47, 48) 4. See the text of the decision. (see para. 49) 5. In the allowance trading scheme introduced by Directive 2003/87 establishing a scheme for greenhouse gas emission allowance trading within the Community, as amended by Directive 2009/29, the sub-objective relating to the preservation of conditions of competition in the internal market is essential. Thus, in Article 10a(1) of that directive, the legislature emphasised the requirement of full harmonisation and, moreover, indicated to the Commission the criteria in accordance with which harmonisation was to be undertaken, namely, in essence, on the basis of benchmarks in sectors and subsectors. In providing for this method of free allocation of allowances, fully-harmonised on a sectoral basis, the legislature gave concrete expression to the essential requirement that distortions of competition in the internal market be minimised. Consequently, the Commission cannot, without being in breach of that requirement, and thus without amending an essential element of Directive 2003/87, lay down rules for the free allocation of allowances that are not fully harmonised and sectoral, such as a provision permitting the free allocation of allowances to certain undertakings faced with undue hardship.
