Professor Notes

In United States v. Zobel, the Ninth Circuit reaffirmed the importance of probable cause under the Fourth Amendment in relation to electronic surveillance.

The court clarified that the specificity of the warrant was crucial in determining its constitutionality, highlighting that well-defined parameters can prevent overly broad searches that infringe on privacy. Additionally, the case underscores how evolving technology challenges established legal frameworks in upholding constitutional rights.
