   [1913 Webster]
    

RETRAXIT, practice. The act by which a plaintiff withdraws his. suit; it is 
so called from the fact that this was the principal word used when the law 
entries were in Latin. 
     2. A retraxit differs from a nonsuit, the former being the act of the 
plaintiff himself, for it cannot even be entered by attorney; 8 Co. 58; 3 
Salk.245; 8 P. S. R. 157, 163; and it must be after declaration filed; 3 
Leon. 47; 8 P. S. R. 163; while the latter occurs in consequence of the 
neglect merely of the plaintiff. A retraxit also differs from a nolle 
prosequi. (q.v.) The effect of a retraxit is a bar to all actions of a like 
or a similar nature; Bac. Ab. Nonsuit, A; a nolle prosequi is not a bar even 
in a criminal prosecution. 2 Mass. R. 172. Vide 2 Sell. Pr. 338; Bac. Abr. 
Nonsuit; Com. Dig. Pleader, X 2. Vide article Judgment of retraxit.
