Quash means to set aside or to void. In a legal context, quash can be used to describe the process of terminating proceedings or motions or to describe the exclusion of evidence from trial. Examples of the usage of quash include "to quash a motion" or "quash evidence."
The methods for quashing depend on the subject matter of the motion to quash. For example, Federal Rule of Civil Procedure 45 sets out the method for quashing a subpoena.
