A Brighton man pleaded not guilty Wednesday to perjury, tampering with an official document, and three other charges stemming from his alleged effort to overturn his conviction using what Suffolk prosecutors dubbed a “novel appellate strategy.’’

David Scher, 33, appeared in Suffolk Superior Court, where he pleaded not guilty to all five charges and was released on personal recognizance, according to Suffolk District Attorney Daniel F. Conley’s office.

According to prosecutors, Scher was convicted in 2014 in Boston Municipal Court on a charge of larceny from a building for stealing a laptop from Suffolk University Law School, where he was then a student. He got a 90-day sentence, suspended for two years, prosecutors said.
