void ab initio

lacked validity from the start, is not obligatory

In law, void means of no legal effect. The Latin phrase, void ab initio means "to be treated as invalid from the outset". An action, document or transaction which is void is of no legal effect whatsoever: an absolute nullity.For example, in many jurisdictions where a person signs a contract under duress, that contract is treated as being void ab initio.There are very critical differents between void ab initio and voidable. Void ab initio can be said void to fail to complied the fundamentals of contract at the beginning.
