"(1) Subject to the following provisions of this Part, the Post Office shall have throughout the United Kingdom the exclusive privilege of conveying letters from one place to another and of performing all the incidental services of receiving collecting and delivering letters
"to enter into and carry out agreements with any person for the carrying on by him, whether as its agent or otherwise, of any of the activities which itself may carry on . . . ."
"all the property, rights and liabilities of the Post Office comprised in the business carried on by the Post Office whether as principal or agent in such parts of post offices as are open to the public and at sub post offices by the Post Office's duly appointed agents on its behalf, immediately prior to the date of the coming into force of the Scheme . . . ."
"In my judgment the words of s.13(1) do not apply to the Department of Employment in the context of this case. They are aimed at professional bodies which grant a qualification for practising, or other bodies granting licences, registration, authorisation or qualification to follow a particular trade or calling. Apart from the plain wording of the section, its position in a group of sections from 11 to 16 in Part II of the Act supports this view. That group of sections is headed "Discrimination by other bodies" (that is to say, bodies other than employers). Section 11 relates to partnerships, section 12 to trade unions, section 14 to vocational training bodies, section 15 to employment agencies and section 16 to the Manpower Services Commission and other employment agencies. Finally, I think the phrase "particular profession or trade" shows that section 13(1) is not concerned with the grant or refusal at government level of a permit to work generally. Accordingly, I dismiss the argument under section 13(1) against the Department of Employment."
