Richard,
My understanding is that CA still allows action without meetings but only for emergencies (which is really the only time they should be used). If my understanding is correct, that is different then being prohibited.
I understand it's easier (and possibly best) to say it's prohibited and encourage the Board to call an emergency meeting vs having an action without meeting. As I said, my understanding is that such action is not prohibited, it's simply greatly limited in CA.
See:
CA Civil Code §4910:
4910. (a) The board shall not take action on any item of business
outside of a board meeting.
(b) (1) Notwithstanding Section 7211 of the Corporations Code, the
board shall not conduct a meeting via a series of electronic
transmissions, including, but not limited to, electronic mail, except
as specified in paragraph (2).
(2) Electronic transmissions may be used as a method of conducting
an emergency board meeting if all directors, individually or
collectively, consent in writing to that action, and if the written
consent or consents are filed with the minutes of the board meeting.
These written consents may be transmitted electronically.
CA Corporations Code §7211 (b)
CA Civil Code §4923 :
4923. An emergency board meeting may be called by the president of
the association, or by any two directors other than the president, if
there are circumstances that could not have been reasonably foreseen
which require immediate attention and possible action by the board,
and which of necessity make it impracticable to provide notice as
required by Section 4920.
