31. The analysis set out above applies whether a second resolution fails to be
adopted because of a lack of votes or because it is vetoed. As I have said before, I do
not believe that there is any basis in law for arguing that there is an implied
condition of reasonableness which can be read into the power of veto conferred on
the permanent members of the Security Council by the UN Charter. So there are no
grounds for arguing that an "unreasonable veto" would entitle us to proceed on the
basis of a presumed Security Council authorisation. In any event, if the majority of
world opinion remains opposed to military action, it is likely to be difficult on the
facts to categorise a French veto as "unreasonable". The legal analysis may,
however, be affected by the course of events over the next week or so, eg the
discussions on the draft second resolution. If we fail to achieve the adoption of a
second resolution, we would need to consider urgently at that stage the strength of
our legal case in the light of circumstances at that time.
Possible consequences of acting without a second resolution
32. In assessing the risks of acting on the basis of a reasonably arguable case, you will
wish to take account of the ways in which the matter might be brought before a court.
There are a number of possibilities. First, the General Assembly could request an
advisory opinion on the legality of the military action from the International Court of
Justice (ICJ). A request for such an opinion could be made at the request of a simple
majority of the States within the GA, so the UK and US could not block such action.
Second, given that the United Kingdom has accepted the compulsory jurisdiction of the
ICJ, it is possible that another State which has also accepted the Court's jurisdiction
might seek to bring a case against us. This, however, seems a less likely option since Iraq
itself could not bring a case and it is not easy to see on what basis any other State could
establish that it had a dispute with the UK. But we cannot absolutely rule out that some
State strongly opposed to military action might try to bring such a case. If it did, an
application for interim measures to stop the campaign could be brought quite quickly (as
it was in the case of Kosovo).
33. The International Criminal Court at present has no jurisdiction over the crime of
aggression and could therefore not entertain a case concerning the lawfulness of any
military action. The ICC will however have jurisdiction to examine whether any military
campaign has been conducted in accordance with international humanitarian law. Given
the controversy surrounding the legal basis for action, it is likely that the Court will
scrutinise any allegations of war crimes by UK forces very closely. The Government has
already been put on notice by CND that they intend to report to the ICC Prosecutor any
incidents which their lawyers assess to have contravened the Geneva Conventions. The
ICC would only be able to exercise jurisdiction over UK personnel if it considered that
the UK prosecuting authorities were unable or unwilling to investigate and, if
appropriate, prosecute the suspects themselves.
34. It is also possible that CND may try to bring further action to stop military action in
the domestic courts, but I am confident that the courts would decline jurisdiction as they
did in the case brought by CND last November. Two further, though probably more
