Cases were held at monthly meetings of the hundred court. The king or one of his reeves, conducted the trial by compurgation.
In compurgation, the one complaining, called the "plaintiff", and the one defending, called the "defendant", each told their story and put his hand on the Bible and swore "By God this oath is clean and true". A slip or a stammer would mean he lost the case. Otherwise, community members would stand up to swear on behalf of the plaintiff or the defendant as to their reputation for veracity. The value of a man's oath was commensurate with his value or wergeld. A man's brothers were usually his compurgators. If these "compurgators" were too few, usually twelve in number, or recited poorly, their party lost. If this process was inconclusive, the parties could bring witnesses to declare such knowledge as they had as neighbors. These witnesses, male and female, swore to particular points determined by the court.
If the witnesses failed, the defendant was told to go to church and to take the sacrament only if he or she were innocent. If he or she took the sacrament, he or she was tried by the process of "ordeal", which was administered by the church. In the ordeal by cold water, he was given a drink of holy water and then bound hand and foot and thrown into water. If he floated, he was guilty. If he sank, he was innocent. It was not necessary to drown to be deemed innocent. In the ordeal by hot water, he had to pick up a stone from inside a boiling cauldron. If his hand was healing in three days, he was innocent. If it was festering, he was guilty. A similar ordeal was that of hot iron, in which one had to carry in his hands a hot iron for a certain distance. The results of the ordeal were taken to indicate the will of God. Presumably a person convicted of murder, i.e. killing by stealth, or robbery [taking from a person's robe, that is, his person or breaking into his home to steal] would be hung and his possessions confiscated. A bishop's oath was incontrovertible. Accused archbishops and bishops could clear themselves with an oath that they were guiltless. Lesser ranks could clear themselves with the oaths of three compurgators of their rank or, for more serious offenses, undergo the ordeal of the consecrated morsel. For this, one would swallow a morsel; if he choked on it, he was guilty.
Any inanimate or animate object or personal chattel which was found by a court to be the immediate cause of death was forfeited as "deodand", for instance, a tree from which a man fell to his death, a beast which killed a man, a sword of a third party not the slayer that was used to kill a man. The deodand was to go to the dead man's kin so they could wreak their vengeance on it, which in turn would cause the dead man to lie in peace.
This is a lawsuit regarding rights to feed pigs in a certain woodland:
"In the year 825 which had passed since the birth of Christ, and in the course of the second Indiction, and during the reign of Beornwulf, King of Mercia, a council meeting was held in the famous place called Clofesho, and there the said King Beornwulf and his bishops and his earls and all the councilors of this nation were assembled. Then there was a very noteworthy suit about wood pasture at Sinton, towards the west in Scirhylte. The reeves in charge of the pigherds wished to extend the pasture farther, and take in more of the wood than the ancient rights permitted. Then the bishop and the advisors of the community said that they would not admit liability for more than had been appointed in AEthelbald's day, namely mast for 300 swine, and that the bishop and the community should have two thirds of the wood and of the mast. The Archbishop Wulfred and all the councilors determined that the bishop and the community might declare on oath that it was so appointed in AEthelbald's time and that they were not trying to obtain more, and the bishop immediately gave security to Earl Eadwulf to furnish the oath before all the councilors, and it was produced in 30 days at the bishop's see at Worcester. At that time Hama was the reeve in charge of the pigherds at Sinton, and he rode until he reached Worcester, and watched and observed the oath, as Earl Eadwulf bade him, but did not challenge it. Here are the names and designations of those who were assembled at the council meeting ..."
