A surety for the appearance of a person taken upon a writ of mainprise. According to Blackstone, and several authorities following his explanation, mainpernors differed from bail in that of appearance: mainpernors could not do either, but were merely sureties for his appearance at the day. Bail were sureties only that the party would be answerable for the special matter for which they stipulate: mainpernors were bound to produce him to answer all charges whatsoever.
