Navarro is 100 Percent Correct in his actions. He should as we all should report violations or suspected violations of the Brown Act to the proper authorities, each and every time it happens.
Sandoval was 100 Percent Wrong in his villification of Navarro's reporting the events.
Now was there wrong doing? Possibly not as there are times when the School Board can all appear at an event and it not be a violation of the Brown Act. That is for the DA's Office to determine.
Think about it. Do one or more members of the School Board appear at a Graduation Ceremony?
There is a clause in the Brown Act that allows for the attendance of Agencies whose Geographic Areas Overlap. As long as there were no CJUSD Issues spoken about amongst the CJUSD Board Members and the meeting was Open to the Public in a Public Place they may be all right under the regulations of the Brown Act.
IF there was a violation, the penalty will be to be told so and told not to do that again. There is no harm in Navarro asking the question. There is all sorts of harm with Sandoval's opposition and apparent oppression of proper governmental oversight by the public.
