The key evidence against Whiteley was seized during a search incident to his arrest, which he claimed was unconstitutional.
The affidavit used to obtain the arrest warrant for Whiteley was based solely on an anonymous tip received by the sheriff.
The Supreme Court held that the information in the affidavit was insufficient to establish probable cause for Whiteley's arrest.
The Court found that the evidence seized during the unlawful arrest should have been excluded from Whiteley's trial.
Whiteley's conviction was therefore overturned by the Supreme Court as unconstitutional.
The case established that police cannot rely solely on an anonymous tip to establish probable cause for an arrest.
