New Jersey Statutes Title 34. Labor and Workmen's Compensation 34 § 15-27

An agreement for compensation may be modified at any time by a subsequent agreement.Upon the application of any party, a formal award, determination, judgment, or order approving settlement may be reviewed within two years from the date when the injured person last received a payment on the ground that the incapacity of the injured employee has subsequently increased. If a party entitled to a review under this section shall become mentally incapacitated within the two-year period, the mental incapacity shall constitute grounds for tolling the unexpired balance of the two-year period, which shall only begin to run again after the party returns to mental capacity. An award, determination , judgment, or order approving settlement may be reviewed at any time on the ground that the disability has diminished. In such case, the provisions of R.S.34:15-19 with reference to medical examination shall apply.
