"SEC. 48. The following-described citizens of the Philippines, occupying lands of the public domain or claiming to own any such lands or an interest therein, but whose titles have not been perfected or completed, may apply to the Court of First Instance of the province where the land is located for confirmation of their claims and the issuance of a certificate of title therefor, under the Land Registration Act, to wit:

"(a) Those who prior to the transfer of sovereignty from Spain to the United States have applied for the purchase, composition or other form of grant of lands if the public domain under the laws and royal decrees then in force and have instituted and prosecuted the proceedings in connection therewith, but have, with or without default upon their part, or for any other cause, not received title therefor, if such applicants or grantees and their heirs have occupied and cultivated said lands continuously since the filing of their applications.

"(b) Those who by themselves or through their predecessors-in-interest have been, in continuous, exclusive, and notorious possession and occupation of agricultural lands of the public domain, under a bona fide claim of acquisition or ownership, for at least thirty years immediately preceding the filing of the application for confirmation of title, except when prevented by war of force majeure. Those shall be conclusively presumed to have performed all the conditions essential to a government grant and shall be entitled to a certificate of title under the provisions of this chapter.

"(c) Members of the national cultural minorities who by themselves or through their predecessors-in-interest have been in open, continuous, exclusive and notorious possession and occupation of lands of the public domain suitable to agriculture, whether disposable or not, under a bona fide claim of ownership for at least 30 years shall be entitled to the rights granted in sub-section (b) hereof."
