The document discusses three Philippine Supreme Court cases on administrative and constitutional law: 1) De la Llana vs Alba - The Court ruled that the legislature can validly remove judges through a law reorganizing the judiciary, as removal is distinguished from abolition of an office. 2) Tio vs Videogram Regulatory Board - The Court upheld a law creating a regulatory board for the video industry and imposing taxes, finding the law embraced a single subject expressed in its title. 3) People vs Maceren - The Court invalidated an administrative order prohibiting electrofishing, finding the agriculture department exceeded its authority as the underlying law did not expressly prohibit the practice.
