 This is certainly true where there is no fraud, but merely inadvertence or ignorance of requirements; for, where there is no malice, punishment should not be inflicted; and the petition should be granted, if a sufficient cause therefor exists.A rescript "in forma commissoria" is valid, if the reason alleged for the grant be true at the time of execution, though false when the rescript was issued.When a rescript is null and void, a new petition is drawn up containing the tenor of the previous concession and cause of nullity, and asking that the defect be remedied.
