Can you explain how these existing laws are subject to the other provisions of the Constitution?
The existing laws continue in force only until they are altered, repealed, or amended by a competent legislature or other competent authority. They are subject to the other provisions of the Constitution, meaning that any changes made must be in compliance with and not violate any constitutional rules or principles. The continuance of these existing laws is only provisional, allowing for time for new legislation to be enacted or for adjustments to be made as needed, but all within the framework of the Constitutional provisions.
