(iv) that when property taken for public use ceases to be so used, the Republic shall accord the former owner or those entitled to the property through such owner, the right of first refusal to reacquire the property. b. All real property held by a person whose certificate of naturalization has been cancelled shall escheat to the Republic unless such person shall have a spouse and/or lineal heirs who are Liberian citizens, in which case the real property shall be transferred to them in accordance with the intestacy law. c. The power of the Legislature to provide punishment for treason or other crimes shall not include a deprivation or forfeiture of the right of inheritance, although its enjoyment by the convicted person shall be postponed during a term of imprisonment judicially imposed; provided that if the convicted person has minor children and a spouse, the spouse or next of kin in the order of priority shall administer the same. No punishment shall preclude the inheritance, enjoyment or forfeiture by others entitled thereto of any property which the convicted person at the time of conviction or subsequent thereto may have possessed. Article 25 Obligation of contract shall be guaranteed by the Republic and no laws shall be passed which might impair this right. Article 26 Where any person or any association alleges that any of the rights granted under this Constitution or any legislation or directives are constitutionally contravened, that person or association may invoke the privilege and benefit of court direction, order or writ, including a judgment of unconstitutionality; and anyone injured by an act of the Government or any person acting under its authority, whether in property, contract, tort or otherwise, shall have the right to bring suit for appropriate redress. All such suits brought against the Government shall originate in a Claims Court; appeals from judgment of the Claims Court shall lie directly to the Supreme Court. CHAPTER IV CITIZENSHIP Article 27 a. All persons who, on the coming into force of this Constitution were lawfully citizens of Liberia shall continue to be Liberian citizens. b. In order to preserve, foster and maintain the positive Liberian culture, values and character, only persons who are Negroes or of Negro descent shall qualify by birth or by naturalization to be citizens of Liberia. c. The Legislature shall, adhering to the above standard, prescribe such other qualification criteria for the procedures by which naturalization may be obtained.
