The commission is not part of the union, but are volunteer appointees from the community. The mayor appoints members in the commission and the appointees are confirmed by the city council.
Here is a PDF describing the commission and its functions.

http://www.honolulupd.org/downloads/HPC2011AnnualReport.pdfOne of its function is to look into complaints by citizens with regards to the police force. I wonder if a well written petition against Kealoha's anti-constitutional statements could be sent to the commission.
The mission of the commission is as follows (sorry for the bold face. I won't be re-typing this one):
