Source: 378 U.S. 108 (1964)
Action: William Aguilar was convicted of possession of narcotics.
Outcome: Conviction upheld by the trial court.
Significance: The case marked the beginning of a legal battle over the validity of the search warrant used in his arrest.
Action: Aguilar appealed his conviction, claiming that the search warrant lacked probable cause.
Outcome: The Court affirmed the lower court's decision.
Significance: The Texas Court of Criminal Appeals ruled that the affidavit supporting the warrant was sufficient under Texas law.
Action: The Supreme Court granted certiorari to review the case.
Outcome: The Court agreed to examine the standards for probable cause and the adequacy of the search warrant.
Significance: This step brought national attention to the issues of Fourth Amendment protections.
Action: The Court issued a decision, ruling on the adequacy of the warrant's supporting affidavit.
Outcome: The Court found that the affidavit did not meet the two-pronged test established in Aguilar v. Texas.
Significance: This ruling established the need for more detailed information to support claims of probable cause in search warrant applications.
At the time the Supreme Court heard the case, the lower courts had upheld Aguilar's conviction based on the sufficiency of the warrant. The primary issue for the Supreme Court was whether the requirements under the Fourth Amendment had been satisfied.
The Supreme Court applied a de novo standard of review regarding the constitutionality of the warrant.
The Supreme Court reversed the judgment of the Texas Court of Criminal Appeals, thereby overturning Aguilar's conviction.
