Actus dei nemini facit injuriam

[Julian]

This is latin word .used in law . It is also called legal maxim
here actus means act
[dei] means god
nemini means kind of no
so the basic meaning is no one [resposible] when something (wrong) is done by god (nature)
eg extreame storm , or big [rainfall] , tsunami etc
and because of this some one god injured then no one will go to jail.
