By the fact itself or by the very nature of the case;

This term is used by Latin-addicted lawyers when something is so obvious that it needs no elaboration or further explanation. For example, it might be said that a blind person, ipso facto, is not qualified to obtain to a driver's license.

Person responsible/interested/ engaged/mixed up in bringing goods illegally into country is said to be concerned with commission of offence - But person who gets their possession after importation, even if with knowledge of their smuggled character, ipso facto cannot be said to be so concerned

Merely because the percentage of medicament in a product is less, does not also ipso facto mean that the product is not a medicament.

If no FIR is recorded and police is not able either to apprehend criminals or recover stolen property, it could not be ipso facto assumed that no theft had taken place.

Mere fact of having facility of blending two types of LPGs does not ipso facto lead to inevitable conclusion that such an activity has been carried out in respect of all clearances.

Merely because holding of shares of subsidiary company could not ipso facto mean that there was mutuality.

Legal maxim

Malum non praesumitur. - Evil is not presumed

Good judgement comes from experience; and experience - well, that comes from bad judgement. (Anon)
