Luxembourg’s finance minister, Jean- Claude Juncker,diplomatically declared after the December meeting that, “ Theresult could have been worse.”

It was pointed out that such a guarantee could take a number of forms such as a declaration before the court, which might or might not be included in the court's ruling, or a diplomatic declaration, which would not necessarily be made during the proceedings.

A diplomat may be declared persona non grata and required to leave the State in accordance with the relevant rules of international law which govern diplomatic relations.

On 22 October 1991 the Council of State “declared diplomatic note No. GM-542 of 22 November 1952 to be nullified ”.

Thus, he describes as implicit actions (of protest) an action before a court, breaking off diplomatic relations, or the declaration of war.

Difficulties might also arise if one State of nationality waived its right to exercise diplomatic protection or declared itself satisfied by the response of the responding State, while the other State continued with its claim.

For example, what would happen if one State of nationality waived its right to exercise diplomatic protection or declared itself satisfied by the response of the responding State, while the other State of nationality continued with its claim?

An injured State could envisage action at a number of levels. To declare a diplomat persona non grata, to terminate or suspend diplomatic relations, to recall ambassadors - such acts are specifically permitted and do not amount to countermeasures.

The Group recommended that an exemption system be established under the authority of the Committee to permit test flights of the Mi-24 helicopter, as well as technical assistance from individuals of foreign or dual nationality. The Group also identified a French national who had facilitated the procurement of technicians for ground-to-air equipment and a Belarusian national, whose Ivorian diplomatic passport declared him as an employee of the Ivorian Ministry of Defence.

It was noted that an appropriate formula should be found to avoid the difficulties that might arise if one of those States were to cease its efforts to exercise diplomatic protection or declare itself satisfied with the reaction of the respondent State, while the other State or States continued to act.
