Section 16. The corporate powers of a county are ordinarily exercised by a board of county commissioners or county supervisors, who represent the county in the management and control of its property and financial interests.

The law is well settled, that courts will not interfere with such boards in the lawful exercise of the jurisdiction committed to them by law, on the sole ground that their actions are characterized by lack of wisdom or sound discretion.10 The principle is well established, that where an inferior tribunal, as a board of county commissioners or supervisors, is invested by law with authority to decide any matter that may be submitted to it, it cannot be compelled to decide a given question, one way or the other. Such a tribunal may be compelled to act, but how it shall decide a given case is always a matter for its judgment, and with the exercise of which no other tribunal or court may interfere.11

The decisions of county Boards and supervisors in the exercise of their judicial discretion are ordinarily conclusive, and not subject to control or review, unless there is a clear abuse of such discretion, or evidence of fraud or collusion.12
