(3) The Contracting State from which the income originate can demand that the responsible authority in the other Contracting State certify residence.
(4) The responsible authorities, in mutual agreement, may decide on the implementation of this Article and, if need be, establish other procedures for the implementation of the tax reductions or exemptions provided for in this Convention.
