notice shall be deemed to have been given to a person if any procedure has been followed which appears to the trustees of the scheme to be adequate to draw his attention to it.
(3) For the purposes of paragraph 2 of Schedule 1, as it applies in respect of proposals for alternative arrangements, notice shall be deemed to have been given to a person if any procedure has been followed which appears to the proposer (within the meaning of that Schedule) and the trustees of the scheme to be adequate to draw his attention to it.
