On 12 Feb. 1680 Levinz was called to the degree of
Serjeant-at-Law and raised to the bench of the
common pleas. He went the
Oxford circuit, and was a member of the commission which tried
Stephen College at the Oxford assizes in August 1681. He was also a member of the special commission which sat at the
Old Bailey in July 1683 to try
Lord Russell for his supposed participation in the
Rye House Plot. Lord Russell having challenged one of the jury for not having a
freehold estate within the city, the point was elaborately argued. All the judges, however, decided against the challenge. Levinz's judgment is reported at some length in
Cobbett's
State Trials. In 1684–85 Levinz was consulted by the king on the question whether a contract by the late king letting out part of the excise to farm was determined by his death, and gave the more sound than courtly advice that it was so. His "quietus" was expected to follow as a matter of course. It was deferred, however, for a time, and he was one of
Jeffreys' colleagues in the
Bloody Assizes, and also helped to try some of the rebels in London. His supersedeas came on 10 Feb. 1685–86. No ground of dismissal was assigned, but probably Levinz was thought to be unsafe on the question of the dispensing power. ==Late cases, death and legacy==
