In the area of public safety, the Legislature has expressly recognized the board of supervisors' exclusive budgetary authority over the district attorney and sheriff. Section 25303 provides, "The board of supervisors shall not obstruct the investigative function of the sheriff of the county nor shall it obstruct the investigative and prosecutorial function of the district attorney of a county." The section goes on to state, "Nothing contained herein shall be construed to limit the budgetary authority of the board of supervisors over the district attorney or sheriff."
