5.2 The Committee has considered the material placed before it by the parties. As to the claims under articles 19, paragraph 2, 25 and 26 of the Covenant, it considers that G.B. has failed to substantiate, for purposes of admissibility, how she was denied her freedom of expression (art. 19, para. 2) and access to public service (art. 25), or how she was discriminated against on the ground of her language (art. 26). The Committee observes that the defacing of road signs does not raise any issues under article 19 and notes that the material before it shows that G.B. was perfectly capable of expressing herself in French, a language she did not claim not to understand, and freely chose to do so; there is no evidence that the sentence pronounced by the Tribunal de Grande Instance of Rennes was intended to prevent her from becoming a civil servant. 5.3 As to the claim of a violation of article 27, the Committee reiterates that France's "declaration" made in respect of this provision is tantamount to a reservation and therefore precludes the Committee from considering complaints against Prance alleging violations of article 27 of the Covenant, jc/ 5.4 The author has also invoked article 2 of the Covenant. The Committee recalls that article 2 is a general undertaking by States parties and cannot be invoked, in isolation, by individuals under the Optional Protocol, d/ Since the author's claims relating to articles 19, 25 and 26 of the Covenant are inadmissible pursuant to article 2 of the Optional Protocol, it follows that she cannot invoke a violation of article 2 of the Covenant. 6, The Human Sights Committee therefore decides: (a) That the communication is inadmissible under article 2 of the Optional Protocol; (b) That this decision shall be communicated to the State party and the author of the communication.
