Tropea, 78 N.J. 309, 313 (1978) (declining to hold that double jeopardy bars retrial of speeding offense but finding that retrial was barred by considerations of fundamental fairness); State v. Gregory, 66 N.J. 510, 519 (1975) (prohibiting multiple prosecution for acts arising out of same arrest under court’s supervisory power to ensure fairness in the administration of justice, although rejecting constitutional attack); State v. De Bonis, 58 N.J. 182 (1971) (as a matter of policy, not due process, defendant who appeals from conviction entered in municipal court and receives trial de novo in county court may not receive harsher sentence on retrial).
