58According to consistent case-law it is necessary, for an action to be admissible, that the basic matters of law and fact relied on be indicated, at least in summary form, coherently and intelligibly in the application itself. While the body of the application may be supported and supplemented on specific points by references to extracts from documents annexed thereto, a general reference to other documents, even those annexed to the application, cannot make up for the absence of the essential arguments in law which, in accordance with the abovementioned provisions, must appear in the application (Case C-52/90Commission v Denmark [1992] ECR I-2187, paragraph 17; orders in Case T-56/92Koelman v Commission [1993] ECR II-1267, paragraph 21, and Case T-154/98Asia Motor France and Others v Commission [1999] ECR II-1703, paragraph 49). The annexes may be taken into consideration only in so far as they support or supplement pleas or arguments expressly set out by applicants in the body of their pleadings and in so far as it is possible to determine precisely what are the matters they contain that support or supplement those pleas or arguments (see, to that effect, Case T-201/04Microsoft v Commission [2007] ECR II-3601, paragraph 99).
