Warrant Exceptions or Permissible Warrantless Search Situations

The Court has stated repeatedly over the decades that searches and seizures conducted without warrants are presumptively unlawful. The Court has also, however, created several exceptions to the warrant requirement. We will spend the next several chapters exploring these exceptions.

One way to think about situations in which warrantless searches are permissible is to place these situations in categories. One common way to categorize these situations is presented in the following list:

For every warrant exception, students should consider: (1) when the exception applies and (2) what the exception allows police to do. In particular, students should note whether probable cause is necessary for the exception to apply and, if not, what other quantum of evidence is required.

In this chapter, we consider the “plain view exception” and the “automobile exception,” each of which has grown over time. In our first case, the Court considered both exceptions.
