145.Section 98 sets out four cases in which harbour authorities may not detain mail-bags. It overrides any other statutory provisions. This replaces section 67 of the Post Office Act 1969 and extends the protection to mail-bags of all universal service providers. The cases are:-
where a universal service provider is carrying the mail-bags himself in connection with the provision of a universal postal service;
where another is carrying the mail-bags of a universal service provider on his behalf either within the UK or to a foreign destination;
where mail-bags of a foreign administration are being carried by a universal service provider: and
where a universal service provider is in charge of the mail-bags of foreign administrations in the United Kingdom in connection with the provision of a universal postal service.
