Cadastral Act means the survey of a large area of land by lots and blocks with the purpose of determining and settling the ownership thereof, and adjudicating to the owners the corresponding titles. In the application of the provision of the Cadastral Act, like in the application of the provision of any other laws, there are legal questions which arise, the interpretation of which may be susceptible of contradictory opinion. After a careful study of the different opinions advanced by both side, we are led to believe that the second theory, that is, the theory that sustains the view that patent issued under the provisions of the Public Land Law does not have the same force and effect as the Torrens title is more in consonance with the spirit of existing legislation on the matter.
