In 1931, a separate
External Great Seal or
Royal Great Seal was created to be used on diplomatic documents which required the signature of
the monarch in London rather than the Governor-General in Dublin. Up to 1931, such documents had been transmitted to the
Dominions Office and the British
Great Seal of the Realm was applied alongside the signature. At the
1930 Imperial Conference, the Free State proposed that a
Dominion should be allowed to send documents via its
High Commissioner in London, bypassing the British government, and to affix its own seal rather than the British one. In January 1931 the Free State government tested its proposed procedure; it applied the 1925 Free State seal to the instrument of ratification for a 1929 treaty between the Free State and Portugal, and sent it to High Commissioner
John W. Dulanty to transmit to
King George V. Dulanty was refused an audience, the British objecting on the grounds that the change in procedure had not been agreed, and that the 1925 seal was not in fact a "great seal" within the terms of the 1922 letters patent, but merely a "private seal of the Governor-General", since it had never been formally approved by the monarch. A compromise was negotiated whereby the Free State would use a separate "external seal" in the custody of its
Minister for External Affairs. Although
Arthur Berriedale Keith claimed in 1934 that "this drastic change in Commonwealth relations was carried out without any discussion in the
British Parliament or intimation by the British Government of the change", in fact Sir
William Davison asked
J. H. Thomas, the
Secretary of State for Dominion Affairs, about it in April 1931; Thomas referred to the
Balfour Declaration of 1926. The external seal, designed by
Percy Metcalfe, had on its reverse a similar image to the 1925 "internal" seal: an Irish harp superimposed upon a Celtic knotwork Greek cross, encircled by the words "SAORSTAT EIREANN" in Gaelic type and further knotwork. Its diameter was , the same as the British Great Seal of the Realm, and had on its obverse the same image of the monarch enthroned as that seal, also designed by Metcalfe, except for the
quartered royal arms above the throne, where the
English arms in first and fourth quarters were switched with the Irish arms in third quarter. The proposal agreed by George V and the ensuing
Department of External Affairs press release both said the new seal would be struck within the Free State. However, the matrix die was made at
Royal Mint Court in London, both sides cut from a single piece of silver by applying a reducing machine to Metcalfe's model. George V formally presented the external seal to John W. Dulanty on 18 January 1932 at
Sandringham House. Keith commented that this marked "the final establishment of the complete international
sovereignty of the Free State and the elimination of any British control". The External Great Seal was used only on
ratifications and
Full Powers, and not always on the latter. Smaller seals, also made by the Royal Mint in 1931, were used on lesser documents: • The "
Signet Seal" was used on
exequaturs receiving foreign diplomats, This seal was used to authenticate the king's "
royal sign-manual", • The "
Fob Seal" was a single-sided seal with the same modified quartered royal arms as the Great Seal. The first use of the External Great Seal was not until 1937, when
George VI sealed Full Powers allowing Francis T. Cremins to sign the
Montreux Convention Regarding the Abolition of the Capitulations in Egypt on behalf of the Free State. Successive governments minimised the use of monarch and the External Great Seal. The state typically conducted bilateral agreements at inter-government level rather than the nominally more prestigious head-of-state level, so that the Minister for External Affairs would apply his
departmental seal to any documents. After signing some multilateral treaties that would have required the External Great Seal for ratification, the state chose instead to wait until the treaty had come into force and then become a party to it by
accession rather than ratification, as the internal Great Seal would suffice for accession. After the
Statute of Westminster 1931, following the Free State's lead, the
Union of South Africa in 1934 passed laws permitting themselves to use their own Great Seals for diplomatic functions. ==Supersession==
