A more thorough explanation:

Soit droit fait al partie is a Law French phrase that means "let right be done to the party." It is typically written on a petition of right and subscribed by the Crown.

One example of the use of this phrase is in the Magna Carta, a document signed by King John of England in 1215. The Magna Carta included a clause that stated:

"Nulli vendemus, nulli negabimus aut differemus rectum aut justitiam."

This translates to "We will sell to no man, we will not deny or defer to any man either justice or right." This clause is essentially a precursor to the idea of "soit droit fait al partie," as it establishes the principle that everyone is entitled to justice and fairness under the law.

Another example of the use of this phrase is in modern legal proceedings, where it may be included in a petition of right. For instance, if a person believes that their rights have been violated by the government, they may file a petition of right asking for redress. The petition may include the phrase "soit droit fait al partie" as a way of emphasizing the importance of justice and fairness in the legal system.

These examples illustrate how the phrase "soit droit fait al partie" is used to emphasize the importance of justice and fairness in legal proceedings. The phrase is a reminder that everyone is entitled to their rights and that the legal system should work to ensure that those rights are protected.
