A more thorough explanation:

Definition: Venit et dicit (vee-nit et dI-sit) is a Latin phrase that means "comes and says." It was commonly used in old-style pleading and is still used in some American jurisdictions today. It is typically used to introduce a plaintiff's statement in a legal proceeding.

Now comes the plaintiff, and respectfully says that the defendant breached their contract by failing to deliver the goods on the agreed-upon date.

In this example, "now comes the plaintiff, and respectfully says" is the introduction to the plaintiff's statement. It is a remnant of the old-style pleading that used the Latin phrase "venit et dicit."

Another example:

Now comes the plaintiff, and respectfully says that the defendant's negligence caused the car accident that resulted in the plaintiff's injuries.

Here, the phrase "now comes the plaintiff, and respectfully says" is used to introduce the plaintiff's claim that the defendant was negligent and caused the accident.
