Numerous statutes protect the integrity of the courts and King's offices by double and treble damages and imprisonment for offenses such as bribery, false informers, conspiracy to falsely move or maintain pleas, champerty [covenant between a litigant and another for the other to have a part or profit in the award in return for maintaining the suit], conflict of interest by court officers taking part in a quarrel pending in court or working any fraud whereby common right may be delayed or disturbed. There had been many abuses, the most common of which was extortion by sheriffs, who gaoled people without cause to make them pay to be released. The 1275 prohibition of maintenance of a quarrel of a party in court by a nonparty was extended in 1327 to all persons, including the king's councilors and ministers, and great men, e.g. by sending letters. In 1346, this prohibition specifically included prelates, earls, barons taking in hand quarrels other than their own, or maintaining them for gift, promise, amity, favor, doubt, or fear, in disturbance of law and hindrance of right. The reason given was that there had been persons disinherited, delayed or disturbed in their rights, and not guilty persons convicted or otherwise oppressed. All great men were required to put out of their service all maintainers who had been retained, and void their fees and robes, without giving them aid, favor, or comfort. This law was not obeyed. The king reserved to himself and his council in its judicial capacity the correction of all breaches of the law which the lower courts had failed to remedy, whether from weakness, partiality, corruption, or jury timidity, and especially when the powerful barons defied the courts. The Chancery also sought to address causes which were impeded in their regular course, which often involved assaults, batteries, and forcible dispossessions. Disputes within the royal household were administered by the King's steward. He received and determined complaints about acts or breaches of the peace within twelve miles around the King's person or "verge". He was assisted by the marshall in the "court of the hall" and by the clerk of the market when imposing fines for trading regulation violations in the "court of the market". Ecclesiastical courts were successful in their competition with the secular courts for jurisdiction over testamentary matters [concerning wills] and intestate succession [no will] to chattels.
