(1) There shall be a Council of Iroij of the Republic of the Marshall Islands.
…
(3) If, in any district, a person or group of persons becomes recognized, pursuant to the customary law⁸ or to any traditional practice, as having rights and obligations analogous to those of Iroijlaplap, that person, or a member of that group nominated by the group, shall be deemed to be eligible to be a member of the Council of Iroij as though he were an Iroijlaplap.
…
(5) If, in the case of any district, there is for any reason no person eligible to be a member of the Council of Iroij in accordance with paragraphs (2) or (3) of this Section, the Council of Iroij shall as soon as practicable proceed, by resolution, to appoint as a member of the Council a person who, in the opinion of the Council, having regard to the customary law and any traditional practice, is qualified by reason of his family ties to a person who, but for that reason, would have been eligible to be a member of the Council from that district.
… (Art. III, Sec. 1)

The Council of Iroij shall have the following functions:
(a) the Council may consider any matter of concern to the Republic of the Marshall Islands, and it may express its opinion thereon to the Cabinet;

(1) The Traditional Rights Court shall be a court of record; shall consist of panels of 3 or more judges selected so as to include a fair representation of all classes of land rights,⁹ including, where applicable, the Iroijiaplap, Iroijedrik, Alap and Dri Jerbal; and shall sit at such times and places and be chosen on such a geographical basis, as to ensure fair and knowledgeable exercise of the jurisdiction conferred by this Section.
(2) The size, membership and procedures of the Traditional Rights Court shall be consistent with paragraph (1) of this Section, and shall be determined by the High Court unless and until the Nitijela makes provision for those matters by Act.
(3) The jurisdiction of the Traditional Rights Court shall be limited to the determination of questions relating to titles or to land rights or to other legal interests depending wholly or partly on customary law and traditional practice in the Republic of the Marshall Islands.
(4) The jurisdiction of the Traditional Rights Court may be invoked as of right upon application by a party to a pending judicial proceeding; but only if the court in which such proceeding is pending certifies that a substantial question has arisen within the jurisdiction of the Traditional Rights Court.
(5) When a question has been certified to the Traditional Rights Court for its determination under paragraph (4), its resolution of the question shall be given substantial weight in the certifying court’s disposition of the legal controversy before it; but shall not be deemed binding unless the certifying court concludes that justice so requires.

(1) Nothing in Article II¹⁰ shall be construed to invalidate the customary law or any traditional practice concerning land tenure or any related matter in any part of the Republic of the Marshall Islands, including, where applicable, the rights and obligations of the Iroijlaplap, Iroijedrik, Alap and Dri Jerbal.
(2) Without prejudice to the continued application of the customary law pursuant to Section 1 of Article XIII,¹¹ and subject to the customary law or to any traditional practice in any part of the Republic, it shall not be lawful or competent for any person having any right in any land in the Republic, under the customary law or any traditional practice to make any alienation or disposition of that land, whether by way of sale, mortgage, lease, license or otherwise, without the approval of the Iroijlaplap, Iroijedrik where necessary, Alap and the Senior Dri Jerbal of such land, who shall be deemed to represent all persons having an interest in that land.

The customary law so declared may include any provisions which, in the opinion of the Nitijela, are necessary or desirable to supplement the established rules of customary law or to take account of any traditional practice.
(2) This Section shall not be construed to authorize the making of any law that would defeat an otherwise valid claim under Article II.
(3) The Nitijela shall not proceed further than the first reading of any Bill or amendment to a Bill which, in the opinion of the Speaker, makes provision for any declaration pursuant to paragraph (1) of this Section unless a joint committee of the Council of Iroij and the Nitijela has been afforded a reasonable opportunity to make a report on the matters dealt within that Bill or amendment, and any such report has been published.
