FACTS:

Cruz was the owner of a parcel of land.  Adjacent to this lot is one wherein Sarmiento had a house built on.  On trying to cause the relocation of her lot, Cruz found out that Sarmiento was encroaching on her property.  When Cruz talked to Sarmiento about constructing a new fence, which will cover her true property, the latter vehemently refused to do so  and threatened Cruz with legal action.  For fear of being sued in court, she sought judicial relief.  The trial  court decided in favor of Cruz.  Sarmiento tried to assail this decision by saying that the issue was on ownership of the portion  of land  and  thus,  the  action  should  have  been  an  accion  reivindicatoria  and not forcible entry.   
 

HELD:

A  careful  reading  of  the  facts  averred  in  said  complaint  filed  by  Cruz reveals that the action is neither of forcible entry nor of unlawful detainer but essentially involves a boundary dispute, which must be resolved in an accion reivindicatoria on the issue of ownership over the portion of a lot.
 
Forcible entry and unlawful detainer cases are distinct actions. 

Cruz cannot belatedly claim that petitioner’s possession of the controverted portion  was  by  mere  tolerance.    The  complaint  didn’t  characterize Sarmiento’s  alleged  entry  on  the  land—whether  legal  or  illegal.    The complaint admitted also of the fact that the fence had already preexisted on the lot when she acquired the same.  
 
This  was  definitely  not  a  situation  obtained  in  and  gave  rise  to  an ejectment  suit  for  two  reasons.    First,  forcible  entry  into  the  land  is  an open challenge to the right of the lawful possessor, the violation of which
right authorizes the speedy redress in the inferior court provided for in the Rules.  Second, if a forcible entry action in the  court is allowed after the lapse  of  a  number  of  years,  then  the  result  may  well  be  no  action  of forcible entry can really prescribe.  No matter how long such defendant is in physical possession, the plaintiff may just throw in a demand, file a suit in court and summarily throw him out of the land.
