Note that, from what I've been told, ARIN staff policy is to approve ALL
requests unless there is a specific section of the NPRM that clearly
says they can't.  They do not feel they have the discretion to deny a
request simply because granting it would be a Bad Idea(tm).

Given the above, the Board should evaluate whether it is necessary to
suspend this (or any other) policy in advance of problematic
applications because by the time such makes its way to Staff, it is too
late for us to do anything about it.  The Board cannot rule on
individual applications (e.g. via appeal, as often proposed) due to
potential conflicts of interest.

IMHO, such a judgment call is best performed by the community by
revising the policy after we have been advised (as in this case) that
the existing policy text is inadequate.  IMHO, it is not in the
community's interests for Staff to be making such decisions of their own
discretion (unless we have explicitly said so, as in Section 12), nor do
we want to put Staff in the position of having to defend such when
challenged.  We owe them clear guidelines that they can implement
impartially, and a Board suspension of policy implies that we (the
community) have failed on that account.
