The mischief which the framers of the Constitution wanted to avoid was carpet-crossing which, from our constitutional history, in the not distant past, had bedevilled the political morality of this country. They had however to allow for a situation where a political party, by reason of internal squabbles, had split into one or more factions. A split or division could arise without any fault of the members of a political party, resulting in a member rightly or wrongly, finding himself in a minority group which may not be big enough, or strong enough, to satisfy the recognition, as a separate political party, of the Federal Electoral Commission. For such a member not to be allowed to join another political party with his faction may be to place him in a position where his right to contest for political office will be lost.
