The Chancellor took jurisdiction of cases of debt, detinue, and account which had been decided in other courts with oath-helping by the defendant. He did not trust the reliance on friends of the defendant swearing that his statement made in his defense was true. An important evidentiary difference between procedures of the Chancery and the common law courts was that the Chancellor could orally question the plaintiff and the defendant under oath. He also could order persons to appear at his court by subpoena [under pain of punishment, such as a heavy fine].
Whereas the characteristic award of the common law courts was seisin of land or monetary damages, Chancery often enjoined certain action. Because malicious suits were a problem, the Chancery identified such suits and issued injunctions against taking them to any court.
The Chancery was given jurisdiction by statute over men of great power taking by force women who had lands and tenements or goods and not setting them free unless they bound themselves to pay great sums to the offenders or to marry them. A statute also gave Chancery jurisdiction over servants taking their masters' goods at his death.
Justices of the Peace, appointed by the Crown, investigated all riots and arrested rioters, by authority of statute. If they had departed, the Justices certified the case to the King. The case was then set for trial first before the king and his council and then at the King's Bench. If the suspected rioters did not appear at either trial, they could be convicted for default of appearance. If a riot was not investigated and the rioters sought, the Justice of the Peace nearest forfeited 2,000s. Justices of the peace were not paid. For complex cases and criminal cases with defendants of high social status, they deferred to the Justices of Assize, who rode on circuit once or twice a year. Since there was no requirement of legal knowledge for a Justice of the Peace, many referred to the "Boke of the Justice of the Peas" compiled about 1422 for them to use. Manor courts still formally admitted new tenants, registered titles, sales of land and exchanges of land, and commutation of services, enrolled leases and rules of succession, settled boundary disputes, and regulated the village agriculture.
All attorneys shall be examined by the royal justices for their learnedness in the law and, at their discretion, those that are good and virtuous shall be received to make any suit in any royal court. These attorneys shall be sworn to serve well and truly in their offices.
Attorneys may plead on behalf of parties in the hundred courts.
A qualification for jurors was to have an estate to one's own use or one of whom other persons had estates of fee simple, fee tail, or freehold in lands and tenements, which were at least 40s. per year in value. In a plea of land worth at least 40s. yearly or a personal plea with relief sought at least 800s., jurors had to have land in the bailiwick to the value of at least 400s., because perjury was considered less likely in the more sufficient men.
In criminal cases, there were many complaints made that the same men being on the grand assize and petty assize was unfair because prejudicial. So it became possible for a defendant to challenge an indictor for cause before the indictor was put on the petty assize. Then the petty assize came to be drawn from the country at large and was a true petty or trial jury. Jurors were separated from witnesses.
Justices of the Peace were to have lands worth 267s. yearly, because those with less had used the office for extortion and lost the respect and obedience of the people.
A Sheriff was not to arrest, but to transfer indictments to the Justices of the Peace of the county. He had to reside in his bailiwick. The sheriff could be sued for misfeasance such as bribery in the King's court.
