Article 26.
No Member of Parliament shall be prosecuted, investigated, arrested, detained or tried in respect of opinions expressed or votes cast in the performance of his official duties.
No Member of Parliament shall be arrested for a serious crime or other major offence, nor shall he be subjected to any other custodial or semi-custodial measure, without the authorization of the Bureau of the House of which he is a member. Such authorization shall not be required in the case of a serious crime or other major offence committed flagrante delicto or when a conviction has become final.
The detention, subjecting to custodial or semi-custodial measures, or prosecution of a Member of Parliament shall be suspended for the duration of the session if the House of which he is a member so requires.
The House concerned shall meet as of right for additional sittings in order to permit the application of the foregoing paragraph should circumstances so require.
