פירוש על בבא בתרא 56:4

A protest not in his pressence (of the possesor) should not be (considered) a protest - If the accuser protests within three years in the pressence of witnesses that (was) not in the pressence of the possesor and he says know that such person is holding my land through theft, it would (should) not be (considered) a protest.

Similar to the warned bull - That we testified that his bull gored and the three times that they testified weren't in his pressence (the owner's), he is not made (placed in the status of being called) warned. Also, warning (in front of) witnesses of 'protest' would not be (called) witnessed, (since) it wasn't in his pressence (of the holder), the protest will be similar to the warning (of the bull). That is (the protest before witnesses only works as a) warning to guard his bull, and also the protest (of the occupancy) is a warning to be careful in (being able to) proving his merit (to be there) and his purchase document.
