(c) the constituent part concerned; or
(d) the committee of management, or an officer, of that part; or

(2) For the purposes of this section:
(a) an act is treated as done in good faith until the contrary is proved; and
(b) a person who has purported to be a member of the committee of management, or an officer, is to be treated as having done so in good faith until the contrary is proved; and
(c) an invalidity in the making or altering of the outline of the proposed withdrawal from amalgamation is not to be treated as discovered before the earliest time proved to be a time when the existence of the invalidity was known to a majority of members of the committee of management or to a majority of the persons purporting to act as the committee of management; and
(d) knowledge of facts from which an invalidity arises is not of itself treated as knowledge that the invalidity exists.
