Article 2. In cases where, in regard to acts (to be limited to those which another person is capable of fulfilling on behalf of the principal) ordered directly by law (inclusive of orders, regulations and by-laws based on the delegation by law;the same to apply hereinafter) or ordered by an administrative public office on the basis of law, a person who is under obligation does not fulfil such acts, and where it is deemed difficult to insure their fulfilment and such non-fulfilment, if left alone, is considered greatly prejudicial to the public interest, the competent administrative office may proceed to execute, of its own accord, the acts which should have been performed by the person under obligation or to cause a third party to perform such acts and collect the expenses therefor from the person under obligation.
