What business can be conducted at an emergency meeting?

The Worshipful Master holds the authority to call a special or emergent meeting of his lodge whenever he deems it necessary, being the sole judge of the emergency that requires it 2. Historical lodge records show such emergent meetings convened to conduct specific degree work, such as raising candidates to the Master Mason degree 1.

In early Masonic history, before the introduction of permanent lodge warrants and established by-laws, all gatherings were extemporary meetings called together for specific operative or speculative purposes and dissolved once the immediate business was concluded 3.
