“Part” means this part, Part 2.5 (commencing with Section 19800), and Part 2.6 (commencing with Section 19815) and those portions of Part 1 (commencing with Section 18000) that confer powers or impose duties on the board or the department.
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.
