Jason is a retired shareholder of the law firm of Bird, Marella, Boxer, Wolpert, Nessim, Lincenberg & Drooks, P.C. He received his Bachelor of Arts degree from the Pennsylvania State University in 1966 and graduated with a JD degree from George Washington University Law School in 1969. From 1969 to 1970, he served as law clerk to the Honorable Andrew Hood, Chief Judge of the District of Columbia Court of Appeals.
Jason was an Assistant United States Attorney for the District of Columbia from 1970 to 1983, where he prosecuted federal and state criminal offenses and defended the government in civil suits. Among Jason's criminal cases that had a broad impact was a rape case in which Jason successfully argued that the victim's prior sexual behavior was not admissible. Jason was then asked by Representative Elizabeth Holtzman's office to consult on the drafting of what became Federal Rule of Evidence 412, which limits the admission of evidence of a victim's prior sexual behavior in the federal courts. During this time Jason also created and taught a course on the subject of expert witnesses at George Washington University Law School.
From 1983 to 2010, Jason's civil practice at Bird Marella focused on business litigation. His criminal practice concentrated on the defense of individuals and entities in white collar investigations in the federal courts. Jason authored or co-authored six articles, several addressing legal ethics about which Jason made a number of presentations to law firms and at bar association programs.
As the Chair of the Brentwood Glen Association's Transportation Committee, Jason led the multi-year opposition to Caltrans' proposal to add a southbound lane on the 405 Freeway near UCLA. At the end of the process Caltrans abandoned its effort to add this lane.
Jason believes that good health for women is good for men's health.
