The appeals board has jurisdiction over any controversy relating to or arising out of Sections 4600 to 4605 inclusive, unless an express agreement fixing the amounts to be paid for medical, surgical or hospital treatment as such treatment is described in those sections has been made between the persons or institutions rendering such treatment and the employer or insurer.
The legislature occasionally skips outline levels.
(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
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.
