If the principle fails, the accessory also fails. When a thing becomes void, the thing contained in it also becomes void. When the original undertaking cannot be carried out, the equivalent thereof is carried out. A thing which is not permissible in itself, may be permissible as an accessory. A thing which is not permissible at the outset may become permissible at some later period.
Continuance is easier than commencement.
A gift becomes absolute only when delivery thereof is taken. A person bestows a thing upon another person by way of gift. Such gift is not binding until delivery thereof has been taken. The exercise of control over subjects is dependent upon the public welfare. Private guardianship is more effective than public guardianship.
