A woman advocate, you can readily imagine, might so influence a court of justice that the laws of the land might suffer feminization.
From the European point of view this would be most undesirable.
The apparently superior rights possessed by English women were also bestowed upon them by a vanished system of laws.

They have descended from Feudalism, in which social order the _person_ did not exist.

The social order consisted of _property_ alone, and the claims of property, that is to say, land, were paramount over the claims of the individual.
Those historic women sheriffs of counties, clerks of crown, chamberlains, and high constables held their high offices because the offices were hereditary property in certain titled families, and they had to belong to the entail, even when a woman was in possession.

The offices were purely titular.

No English woman ever acted as high constable.
