David Wynn Miller (September 17, 1949 – 2018), also styled :David-Wynn: Miller or David-Wynn: Miller, was an American tool and die welder and leader of a tax protester group within the Sovereign citizen movement.
He has been described as having far-right views and as being a proponent of conspiracy theories.
He was a proponent of the use of certain syntax he created to be used by people involved in legal proceedings.
He referred to his syntax as QUANTUM-LANGUAGE-PARSE-SYNTAX-GRAMMAR which he asserts constitutes "correct sentence structure communication syntax." People seeking remedy with Miller's syntax in court have not met with success.
