, who wrote the ponencia According to Chief Justice Concepcion, the constitutional basis for search warrants in private residences are: (1) that they may only be granted by the Courts if probable cause is determined and that (2) the warrant shall particularly describe the things to be seized. This can be found in the
Bill of Rights of the
1935 Constitution, or in Article III, Section 1(3) which states, (3) The right of the people to be secure in their persons, houses, papers, and effects against unreasonable searches and seizures shall not be violated, and no warrants shall issue but upon probable cause, to be determined by the judge after examination under oath or affirmation of the complainant and the witnesses he may produce, and particularly describing the place to be searched, and the persons or things to be seized. This is reiterated in the far lengthier prevailing
1987 Constitution, which emphasized that the term "search and seizures" were of any nature or type, as well as the personal involvement of the judge as a result of this case.SECTION 2. The right of the people to be secure in their persons, houses, papers, and effects against unreasonable searches and seizures of whatever nature and for any purpose shall be inviolable, and no search warrant or warrant of arrest shall issue except upon probable cause to be determined personally by the judge after examination under oath or affirmation of the complainant and the witnesses he may produce, and particularly describing the place to be searched and the persons or things to be seized. Since this was not determined through probable cause, it was not admissible evidence. The Court abandoned the doctrine set in Moncado vs. People's Court (80 Phil. 1) that unconstitutionally obtained evidence may still be admissible. This was because the protection of the right to privacy may be violated, which is the essence of the exclusionary rule or the doctrine of the
fruit of the poisonous tree. This was the origin of the exclusionary rule. The term,
fruit of the poisonous tree was not expressly mentioned, C.J. Concepcion used the term exclusionary rule, and the rule was the basis of the law of this case, which meant that evidence that is unconstitutional cannot be used to investigate or prosecute another party. Essentially the rule also ensured that general warrants or scatter-shot warrants cannot be issued to allow law officers to go on
fishing expeditions and obtain evidence against the accused, as this is the only practical means to enforce the constitutional injunction against unreasonable searches and seizures in the Bill of Rights found in Article III of both the contemporary and modern constitutions. == Aftermath ==
