Justice Antonin Scalia maintained a strong support for originalism and textualism as he served on the Supreme Court from 1986 to his passing in 2016. Through these interpretive strategies the Court established a major influence on its constitutional interpretation practices.​
Using the principles of Originalism which he supported Justice Scalia believed that the Constitution must be interpreted by its original understanding at the time of ratification. This interpretive approach seeks to restrict court activism by maintaining a strict approach toward how the text was written historically. Scalia rigorously applied his originalist doctrines to oppose prevailing interpretations especially through his opposition to using evolving societal changes with the Constitution. ​
During statutory interpretation Scalia prioritized reading the precise words in legislation above incorporating outside materials or intent of the law creators. The methodology of text-based statutes analysis adopted by courts evolved under this influence towards a new textual methodology. Justice Elena Kagan stated that judicial interpretations today show Scalia's influence since "we are all textualists now." ​
Scalia gained recognition for his quick-witted and attention-grabbing method of opinion writing in addition to his interpretative approaches. His opinions especially dissents were carefully constructed to create long-lasting effects which reached both professional legal readership and public audiences. According to his thinking strong expressive language provided an essential means to deliver complicated legal concepts clearly. ​
The approach that Scalia used when he served on the Supreme Court continues to influence the current judicial decisions made by the court. Originalism and textualism serve as guiding approaches that judicial reasoning follows under his influence since many judges now emulate his philosophies. The extended impact of Scalia's influence on the Court's law confirms that the current Supreme Court remains essentially "Antonin Scalia's Supreme Court.
