(1B) If the same person has, or the same persons have together, a controlling interest under sub-section (1C) in each of two businesses, the persons who carry on those businesses constitute a group and each is a member of the group. (1C) For the purposes of sub-section (1B), the same person has, or the same persons have together, a controlling interest in each of two businesses if that person has, or those persons have together, a controlling interest under any of the following paragraphs in one of the businesses and a controlling interest under the same or another of the following paragraphs in the other business--
...
(e) a person has, or persons have together, a controlling interest in a business, being a business carried on under a trust, if that person (whether or not as the trustee of, or beneficiary under, another trust) is the beneficiary, or those persons (whether or not as the trustees of, or beneficiaries under, another trust) are together the beneficiaries, in respect of 50 per centum or more of the value of the interests in the trust first-mentioned in this paragraph;
...
(1E) A person who, as the result of the exercise of a power or discretion by the trustee of a discretionary trust or by any other person or by that trustee and other person, may benefit under that trust is deemed, for the purposes of this Act, to be a beneficiary in respect of 50 per centum or more of the value of the interests in that trust.

(1I) For the purposes of this Act, if a person is an employer who is a member of a group, a reference to an employer does not have effect in relation to that person otherwise than as a member of that group. (1J) If the Commissioner is satisfied, having regard to the nature and degree of ownership and control of the businesses, the nature of the businesses and any other matters the Commissioner considers relevant, that a business carried on by a member of a group, including a group constituted by reason of section 9A(2), is carried on independently of, and is not connected with the carrying on of, a business carried on by any other member of that group, the Commissioner may exclude the member from that group.
...
(2) If a person is a member of two or more groups (whether or not by reason of this sub-section), all the members of those groups constitute one group for the purposes of this Act." [8]
