(Standing Order 116 in the Fourth Edition, May 2006 ).
Standing Order 116 (10) states "A Member may not interrupt any Member who is speaking by any disorderly expression or remarks, running commentary or IN ANY OTHER DISODERLY MANNER."
In some jurisdictions, sleeping and snoring in The House is tantamount to disorderly and discourteous behaviour .
In regard to sleeping (plus snoring ) in The House, the Speaker can signal the Sergeant-at-Arm to walk gracefully to the sleeping Member and tactfully wake him or her up.
However, in unusual circumstance where more Members are sleeping at the same time, the Speaker can adjourn the House momentarily and let the Members " liven up " a bit.
However, if the Speaker himself or herself is also in slumber land, OTI VAKADUA!
