“Thence the course of the Kagera downstream to meet the western boundary of Bugufi;

“Thence this boundary to its junction with the eastern boundary of Urundi;

“The Mandatory shall not establish any military or naval bases, nor erect any fortification, nor organise any native military force in the territory except for local police purposes and for the defence of the territory.

Article 5

“The Mandatory:

  • “1. Shall provide for the eventual emancipation of all slaves and for as speedy an elimination of domestic and other slavery as social conditions will allow;
  • “2. Shall suppress all forms of slave trade;
  • “3. Shall prohibit all forms of forced or compulsory labour, except for essential public works and services, and then only in return for adequate remuneration;

“The Mandatory will promulgate strict regulations against usury.

Article 7

“The Mandatory shall secure to all nationals of States Members of the League of Nations the same rights as are enjoyed in the territory by his own nationals in respect of entry into and residence in the territory, the protection afforded to their person and property, the acquisition of property, movable and immovable, and the exercise of their profession or trade, subject only to the requirements of public order, and on condition of compliance with the local law.

[Page 206]

“Further, the Mandatory shall ensure to all nationals of States Members of the League of Nations, on the same footing as to his own nationals, freedom of transit and navigation, and complete economic, commercial and industrial equality; provided that the Mandatory shall be free to organise essential public works and services on such terms and conditions as he thinks just.

“Concessions for the development of the natural resources of the territory shall be granted by the Mandatory without distinction on grounds of nationality between the nationals of all States Members of the League of Nations, but on such conditions as will maintain intact the authority of the local Government.

Article 9

“The Mandatory shall apply to the territory any general international conventions already existing, or which may be concluded hereafter, with the approval of the League of Nations, respecting the slave trade, the traffic in arms and ammunition, the liquor traffic and the traffic in drugs, or relating to commercial equality, freedom of transit and navigation, aerial navigation, railways, postal, telegraphic and wireless communication and industrial, literary and artistic property.

“The Mandatory shall co-operate in the execution of any common policy adopted by the League of Nations for preventing and combating disease, including diseases of plants and animals.

[Page 207]

Article 10

“The Mandatory shall be authorised to constitute the territory into a customs, fiscal and administrative union or federation with the adjacent territories under his own sovereignty or control, provided always that the measures adopted to that end do not infringe the provisions of this mandate.

Article 11

“The Mandatory shall make to the Council of the League of Nations an annual report to the satisfaction of the Council, containing full information concerning the measures taken to apply the provisions of this mandate.

“A copy of all laws and regulations made in the course of the year and affecting property, commerce, navigation or the moral and material well-being of the natives shall be annexed to this report.

Article 12

“The consent of the Council of the League of Nations is required for any modification of the terms of this mandate.

Article 13

“The Mandatory agrees that if any dispute whatever should arise between the Mandatory and another Member of the League of Nations relating to the interpretation or the application of the provisions of the mandate, such dispute, if it cannot be settled by negotiation, shall be submitted to the Permanent Court of International Justice provided for by article 14 of the Covenant of the League of Nations.

“States Members of the League of Nations may likewise bring any claims on behalf of their nationals for infractions of their rights under this mandate before the said court for decision”; and
