proceeding, or a plaintiff in a civil suit, without probable cause, by a 
regular process and proceeding, which the facts did not warrant, as appears 
by the result.

though without sufficient cause. 1 Penna. R. 235.

information given by them to their fellow jurors, on which a prosecution is 
founded. Hardin, 556. Such action lies against a plaintiff in a civil action
