Question: AS number preservation

Hello,

 I hope this is the right forum for asking this question... if not, please
direct me to the right place. TIA.

 I have a question which I was hoping someone could answer: let us assume that
an organization already has an AS number, due to, say, a multihomed connection
to two other AS's.
 This organization now removes one of these connections, and is left with a
single-homed connection. However, the organization may still wish to regain a
multihomed connection in the future, and therefore would like to keep their AS
number.
 What are the rules governing such a case? Will the AS number be preserved? Will
it be taken from the organization? If so, how long does the organization have to
reestablish a multihomed connection? Is there any document that deals with this
issue (I havent found anything relevant in RIPE-181 or RIPE-185)

 Many 10x,

  Sincerely,            \'"'/
