Brehon

One difference is Precident; In English law a decision of a judge is binding on other judges who have similar cases, and if you break the law, the judge may say: "I want to send Precident prison life, but d'une such penalty is two years "and it gives you two years in prison.

Brehon law was quite similar to the original. The Brehon work is the English spelling of the Irish word for the judge. The difference was, however, that the areas of Irish law was written (originally memorized by heart) so that the judge was limited to enforcement against these leaflets. Rather than being fixed prescidence by the judge, the books dictated the decision.

Another factor that is important to the story is primogeneture. In English law, the first born male inherited all the father's property, so the Lord has been adopted by the direct male line. Under Irish law, the property was divided among all men, has divided the oldest and the youngest got the first choice (other younger divded he and the oldest was awarded the first choice, do not remember ), which led to ensure that the division was fair. Also the inheritance of the Lord was not the direct male heir, but to all those who descended from the same grandfather (not only your brothers, but first, second, third cousins, uncles, etc. were eligible for inheritance). Usually, he went to a son, but like in the movies godfather, not necessarily the eldest (Freido) but the best (Michael).

Brehon law permitted divorce. The woman was taken to leave his property with her. In English law, and in most countries, when a man marries a woman, he received a dowry (paid to marry) and the wedding ceremony consisted of the father walking his daughter and giving him physically man. Brehon Law, it all happened, the dowry was not given, but his assurance that it would always be able to feed themselves and children should be a waste of human space.

Brehon law, children were eligible to inherit, even if the man was not married to the mother. A dispute about real father of the child were resolved by waiting for the child to grow up and see that it looked like (in English law, the father of the child was not relevant if the mother was not married to him).

A major difference is that there was no sentence of death. In English law, if you killed a man you have been hanged. Under Irish law, you had to pay a price for the body and pay compensation for his grade. The Irish do not use coins (they knew about them from contact with the Romans and Saxons, but they did not take to them), the base currency was a Cumali, a slave, milsh and a cow (a cow producing milk) so if you killed a man whom you paid 7 cows, and if he was a lord, another 7 Cumali (I think) or 49 cows. To be a free man you need to have 7 cows and a bull. Anything less and you were a dependent. If you have not paid, then the family had to pay, and if they refused then you were an outlaw (outside the law) and could be hunted, killed or enslaved by the family and There was nothing of your family could do about it. If you killed a priest, woman or child (collectively the innocent) you had to pay a great honor.

There are many more, but there are books written on this subject, check if your library has a book by Fergus Kelly called "Guide to Irish law at the beginning".
