Diplomatic Immunities (Conferences with Common wealth Countries) Act, 1963

This 1963 Act extends limited diplomatic-style immunity to representatives of other Commonwealth countries' governments when they attend conferences held in Pakistan, along with their official staff. It is explicitly reciprocal: Section 3 lets the Federal Government apply the Act to a particular Commonwealth country only once it is satisfied that country provides equivalent immunity to Pakistani representatives attending conferences there, declared by Gazette notification.

Section 4 sets up the administrative mechanism — for each qualifying conference held in Pakistan, the Secretary of the government ministry responsible for convening or sponsoring it must compile and publish, in the official Gazette, a list of the attending representatives and their official staff, separately identifying those who are (or are treated as) Pakistani citizens from those who are not. The Secretary can amend this list as people's status changes, with amendments also published in the Gazette.

Section 5 grants the substantive immunity: a listed representative gets immunity from suit and legal process, and inviolability of residence, official premises, and archives, equivalent to that of an envoy of a foreign power. A listed member of the official staff gets immunity from suit and legal process on the same basis. However, if a representative or staff member is (or is treated as) a Pakistani citizen, this immunity only covers things done or omitted in the course of their official duties at the conference.

Section 6 makes the published Gazette list conclusive proof, in any legal proceeding, of whether a particular person was or was not included among those entitled to immunity at the relevant time. This is a specialised diplomatic-protocol law relevant to hosting international Commonwealth conferences in Pakistan.
