A probate court is hereby established for each county, which shall be a court of record, and, until otherwise provided by law, shall have the same jurisdiction as heretofore exercised by the probate courts of New Mexico and shall also have jurisdiction to determine heirship with respect to real property in all proceedings for the administration of decedents’ estates. The legislature shall have power from time to time to confer upon the probate court in any county in this state jurisdiction to determine heirship in all probate proceedings, and shall have power also from time to time to confer upon the probate court in any county in this state general civil jurisdiction coextensive with the county; provided, however, that such court shall not have jurisdiction in civil causes in which the matter in controversy shall exceed in value three thousand dollars ($3,000.00) exclusive of interest and cost; nor in any action for malicious prosecution, slander and libel; nor in any action against officers for misconduct in office; nor in any action for the specific performance of contracts for the sale of real estate; nor in any action for the possession of land; nor in any matter wherein the title or boundaries of land may be in dispute or drawn in question, except as title to real property may be affected by the determination of heirship; nor to grant writs of injunction, habeas corpus or extraordinary writs. Jurisdiction may be conferred upon the judges of said court to act as examining and committing magistrates in criminal cases, and upon said courts for the trial of misdemeanors in which the punishment cannot be imprisonment in the penitentiary, or in which the fine cannot be in excess of one thousand dollars ($1,000). A jury for the trial of such cases shall consist of six men. The legislature shall prescribe the qualifications and fix the compensation of probate judges. (As amended September 20, 1949.)
