Article 2
1. Member States shall take the measures necessary to prevent the entry into, or transit through, their territories of: (a) natural persons who are responsible for, provide financial, technical or material support for or are otherwise involved in: (i) manufacturing, acquiring, possessing, developing, transporting, stockpiling or transferring chemical weapons; (ii) using chemical weapons; (iii) engaging in any preparations for the use of chemical weapons; (b) natural persons who assist, encourage or induce any natural or legal person, entity or body to engage in any activity referred to in point (a) of this paragraph and thereby cause or contribute to a danger that such activities may be carried out; and (c) natural persons associated with the natural persons listed in points (a) and (b); as listed in the Annex. 2. Paragraph 1 shall not oblige a Member State to refuse its own nationals entry into its territory. 3. Paragraph 1 shall be without prejudice to the cases where a Member State is bound by an obligation of international law, namely: (a) as a host country of an international intergovernmental organisation; (b) as a host country to an international conference convened by, or under the auspices of, the United Nations; (c) under a multilateral agreement conferring privileges and immunities; or (d) pursuant to the 1929 Treaty of Conciliation (Lateran Pact) concluded by the Holy See (Vatican City State) and Italy. 4. Paragraph 3 shall be considered as applying also in cases where a Member State is host country of the Organisation for Security and Cooperation in Europe (OSCE). 5. The Council shall be duly informed in all cases where a Member State grants an exemption pursuant to paragraph 3 or 4. 6. Member States may grant exemptions from the measures imposed under paragraph 1 where travel is justified on the grounds of urgent humanitarian need, or on grounds of attending intergovernmental meetings and those promoted or hosted by the Union, or hosted by a Member State holding the Chairmanship in office of the OSCE, where a political dialogue is conducted that directly promotes the policy objectives of the restrictive measures, including implementing the legal prohibitions against chemical weapons and the achievement of chemical weapons disarmament. Member States may also grant exemptions from the measures imposed under paragraph 1 where entry or transit is necessary for the fulfilment of a judicial process. 7. A Member State wishing to grant exemptions referred to in paragraph 6 shall notify the Council in writing. The exemption shall be deemed to be granted unless one or more of the Council members raises an objection in writing within two working days of receiving notification of the proposed exemption. Should one or more of the Council members raise an objection, the Council, acting by a qualified majority, may decide to grant the proposed exemption. 8. Where, pursuant to paragraphs 3, 4, 6 or 7 a Member State authorises the entry into, or transit through its territory of persons listed in the Annex, the authorisation shall be strictly limited to the purpose for which it is given and to the persons directly concerned thereby.
