Albert Barnes Commentary 2 Chronicles 19:10

"And whensoever any controversy shall come to you from your brethren that dwell in their cities, between blood and blood, between law and commandment, statutes and ordinances, ye shall warn them, that they be not guilty towards Jehovah, and so wrath come upon you and upon your brethren: this do, and ye shall not be guilty." — 2 Chronicles 19:10 (ASV)

The Jews who “lived in the cities,” if dissatisfied with the decision given by the provincial judges, could therefore appeal the case to Jerusalem, to a court of appeal.
