175Article 134(1) of the Rules of Procedure provides that the unsuccessful party is to be ordered to pay the costs if they have been applied for in the successful party’s pleadings. However, according to Article 135(1) of the Rules of Procedure, exceptionally, if equity so requires, the Court may decide that an unsuccessful party is to pay only a proportion of the costs of the other party in addition to bearing its own costs. In addition, according to Article 135(2) of those Rules, the Court may order a party, even if successful, to pay some or all of the costs, if this appears justified by the conduct of that party, including before the proceedings were brought. The Court may, inter alia, order an institution whose decision has not been annulled to pay the costs by reason of the inadequacy of that decision, which may have led an applicant to bring an action (see judgment of 22 April 2016, Italy and Eurallumina v Commission, T‑60/06 RENV II and T‑62/06 RENV II, EU:T:2016:233, paragraph 245 and the case-law cited).
