5.4.1 Subpoenas and Other Legal Requests
All subpoenas and other legal requests received by the IAOC
or the IETF will be published on the IAOC website together
with their responses.
Reason for Change: Greater transparency.
Some such requests may include the requirement that they not be revealed.
I don't think it wise to have a published policy which doesn't allow for
such a legal restriction.
