Editing Sui generis (section)

===Statutory law===
{{+rs|date=March 2016}}
In [[statutory interpretation]], ''sui generis'' refers to the problem of giving meaning to groups of words where one of the words is ambiguous or inherently unclear.

In road traffic law, a statute may require consideration of large vehicles separately from other vehicles. The word "large" is ambiguous ''per se'' but may be considered "heavy". The relevant legislation (in Australian law) contain sections called "Terms used" or "Definitions" that itemise all words deemed ambiguous and confers specific interpretations consistent with natural language. One indicates "heavy vehicle" means a vehicle with a GVM over 4.5 tons, and GVM means "gross vehicle mass", the maximum loaded mass of the vehicle. Further explanations cover various contingencies. Thus, "large" is equivalent to "heavy" and is (for this unique case) clearly defined ''sui generis''.

In U.S. attorney admissions, an applicant for admission to the practice of law may be referred to the state committee on character and fitness, where proceedings are "neither civil nor criminal, but are sui generis".<ref>{{cite web | url=https://govt.westlaw.com/azrules/Document/N2EC12DE03E3E11EDA13DAA05478457BE?viewType=FullText&originationContext=documenttoc&transitionType=CategoryPageItem&contextData=(sc.Default) | title=A.R.S.
