5. Common seal of Board

The common seal of the Board must bear such device as the Board may approve and the seal may be broken, changed, altered or made anew by the Board as it may think fit.

The common seal must be kept in the custody of the president and must be authenticated by the president or other member acting in the president’s absence.

Any document purporting to be sealed by the common seal and authenticated as provided under subsection (2) is, until the contrary is proved, deemed to be validly executed.
