60It follows from Article 44(1)(c) in conjunction with Article 48(2) of the Rules of Procedure that the original application must contain the subject-matter of the proceedings and a summary of the pleas in law relied on, and that new pleas in law may not be introduced in the course of the proceedings unless they are based on matters of law or of fact which come to light in the course of the procedure. However, a submission or argument which may be regarded as amplifying a plea made previously, whether directly or by implication, in the original application, and which is closely connected therewith, will be declared admissible (see, to that effect, Case 108/81Amylum v Council [1982] ECR 3107, paragraph 25; Case T-37/89Harming v Parliament [1990] ECR II-463, paragraph 38; and Case T-118/96Thai Bicycle v Council [1998] ECR II-2991, paragraph 142, and case-law cited).
