John P. Robertson II — Sussex and Warren County Criminal Defense Attorney

Experienced New Jersey Criminal and DWI Defense Lawyer with Prosecutorial Background

John P. Robertson II brings nearly four decades of New Jersey criminal defense experience to the Tormey Law Firm. Admitted to practice in New Jersey in 1987, John has spent his career defending individuals against the full range of criminal charges in Sussex County, Warren County, and throughout New Jersey — from DWI/DUI and assault offenses to drug crimes, weapons offenses, restraining order matters, and sex crime allegations.

John began his legal career in 1986 as an Assistant Prosecutor with the Morris County Prosecutor’s Office, where he gained firsthand experience evaluating evidence, presenting cases to grand juries, and working alongside law enforcement. Since transitioning to private practice in 1989, he has dedicated himself to defending the rights of those facing criminal accusations — using his prosecutorial background to anticipate the State’s strategy and identify weaknesses in the case against his clients.

Strong Local Roots in Sussex and Warren Counties

John’s connection to the northwest New Jersey region runs deep. He served as a former Member of the District X Ethics Committee for Morris and Sussex Counties, giving him an established presence in the Sussex County legal community. His career as a Morris County Assistant Prosecutor and decades of practice in nearby Morris County Superior Court provide him with direct familiarity with the courts, judges, and prosecutorial culture across the northwest New Jersey region — including the Sussex County Superior Court in Newton and the Warren County Superior Court in Belvidere.

Why a Former Prosecutor Matters in Your Case

A criminal conviction in New Jersey can result in jail time, heavy fines, license suspension, a permanent record, and serious collateral consequences affecting employment, immigration status, professional licensing, and firearms eligibility. Successfully defending these cases requires more than general courtroom experience — it requires a deep understanding of how prosecutors think, what evidence they prioritize, and where their cases are most vulnerable to challenge.

John’s former role as an Assistant Prosecutor gives him unique insight into:

• How prosecutors evaluate the strength of a case at intake
• What evidence the State considers essential to securing a conviction
• How probable cause is established (and where it can be challenged)
• How Pre-Trial Intervention (PTI) and conditional discharge applications are reviewed and approved
• What arguments resonate with judges in plea negotiations
• How sentencing recommendations are formulated and where they can be reduced

This insider perspective gives John’s clients a real strategic advantage — particularly in cases where the path to a favorable outcome depends on negotiating with the prosecutor’s office.
