The political executive — the Prime Minister and Cabinet — must have the support of the majority in the House of Commons to stay in power. If it loses that support on a question of confidence, it must resign or call for an election.
The legislature occasionally skips outline levels.
For example:
(3) A person may apply [...]
(4)(a) A person petitioning for relief [...]
In this example, (3), (4),
and (4)(a) are all outline levels, but
(4) was
omitted by its authors. It's only implied. This presents an
interesting challenge when laying out the text. We've
decided to display a blank section with this note, in order
to aide readability.
