The term legal technicality is a casual or colloquial phrase referring to a technical aspect of law. The phrase is not a term of art in the law; it has no exact meaning, nor does it have a legal definition. It implies that that strict adherence to the letter of the law has prevented the spirit of the law from being enforced. However, as a vague term, the definition of a technicality varies from person to person, and often is simply used to denote any portion of the law which interferes with the user of the term's desired outcome. [1]
Some legal technicalities govern legal procedure, enable or restrict access to courts, and/or enable or limit the discretion of a court in handing down judgment. These are aspects of procedural law. Other legal technicalities deal with aspects of substantive law, that is, aspects of the law which articulate specific criteria that a court uses to assess a party's compliance with or violation of, for example, one or more criminal laws or civil laws.[2]
In the United States, Constitutional guarantees such as those included in the Fourth and Fifth amendments to protect an accused from unreasonable search and seizure or from self-incrimination have been referred to as "technicalities" by critics of court decisions based on them, even though they are foundations of the American legal system rather than obscure fine points. A commonly cited example would be attempted prosecution of a crime that was discovered by illegally obtained evidence. Such cases may be dismissed based on lack of evidence as the illegally obtained evidence would not be allowed to be the basis of the prosecution's case (called the "fruit of the poisonous tree" doctrine). Other procedural "technicalities" arise from common law as well, for example, the standard procedural defenses of laches and estoppel applicable within civil law.
Some examples of technical aspects of legal procedure are:
