Ex facto has a Latin origin. It is pronounced as 'eks fak-toh'. When something is done ex facto or something is ex facto, it is said to be done 'according to the facts'. Ex facto is also used as 'ex post facto'. In this phrase, the act or thing is described as done or made afterwards, especially when it has a retroactive effect. Thus, here even though the action takes place in the present, that is the action of doing or making a law or a rule, its application takes effect from a date in the past.
Ex facto is usually used in legal context or concerns laws and rules. Example of ex facto could be: ex facto jus oritur. This sentence indicates that 'the law arises from the fact'. The law cannot take effect unless the nature of the crime is known.
