If the basic jurisdictional facts provided in a statute turn out to be unsupported, an administrative agency’s jurisdiction may be lost.[i]  However, a failure to exercise jurisdiction does not result in its loss, even though it indicates a practical construction that the power does not exist [ii]

An administrative tribunal vested with jurisdiction of a matter does not lose jurisdiction by:

• not giving sufficient weight to evidence, or
• by rejecting proper evidence, or
• by admitting that is improper.[iii]

Moreover, jurisdiction is not divested by an error of judgment in reaching the result.[iv]
