If the defendant does not appear, upon proof of service or publication the Senate may, of its own motion or for cause shown, assign another day for hearing the impeachment, or may proceed to trial and judgment in the absence of the defendant.
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.
