(c) The Committee shall deal with a matter referred to it only after it has ascertained that all available domestic remedies have been invoked and exhausted in the matter, in conformity with the generally recognized principles of international law.

The Committee may also communicate only to the States Parties concerned any views that it may consider relevant to the issue between them. In every matter, the report shall be communicated to the States Parties concerned. 2. The provisions of the present article shall come into force when ten States Parties to the present Convention have made a declaration under paragraph 1 of the present article. Such declarations shall be deposited by the States Parties with the Secretary-General of the United Nations, who shall transmit copies thereof to the other States Parties. A declaration may be withdrawn at any time by notification to the Secretary-General. Such a withdrawal shall not prejudice the consideration of any matter that is the subject of a communication already transmitted under the present article; no further communication by any State Party shall be received under the present article after the notification of withdrawal of the declaration has been received by the Secretary-General, unless the State Party concerned has made a new declaration. Article 77 1. A State Party to the present Convention may at any time declare under the present article that it recognizes the competence of the Committee to receive and consider communications from or on behalf of individuals subject to its jurisdiction who claim that their individual rights as established by the present Convention have been violated by that State Party. No communication shall be received by the Committee if it concerns a State Party that has not made such a declaration. 35
