2. Each State Party shall take such measures as may be necessary to establish or maintain, in accordance with its legal system and constitutional principles, an appropriate balance between any immunities or jurisdictional privileges accorded to its public officials for the performance of their functions and the possibility, when necessary, of effectively investigating, prosecuting and adjudicating offences established in accordance with this Convention.
二、各缔约国均应当根据本国法律制度和宪法原则采取必要措施以建立或者保持这样一种适当的平衡：即既照顾到为公职人员履行其职能所给予的豁免或者司法特权，又照顾到在必要时对根据本公约确立的犯罪进行有效的侦查、起诉和审判的可能性。
