Should any doubt or difficulty arise as to whether an act of the Land legislature is compatible with the law of the Realm, the competent authorities of the Realm or Land may appeal to the decision of a Supreme National Court of Judicature; as may be subsequently determined by an act of the Realm.
Acts of the Realm are administered by authorities of the Lands except in so far as may be otherwise determined by acts of the Realm.
Article 15.
The Government of the Realm has the right of supervision over those matters in which it has the right of legislation.
The Government of the Realm may lay down general directions where acts of the Realm are administered by the authorities of the Lands. It may send commissioners to the authorities of the Lands, and with their concurrence to subordinate authorities in order to supervise the execution of the acts of the Realm.
The Land Governments are bound to remedy, on demand of the Government of the Realm, any deficiencies which may have appeared in the course of executing the acts of the Realm. In cases of dispute, both National Government of the Realm and Governments of the Lands may appeal to the decision of a Supreme Court of Judicature, except where an act of the Realm declares another court to be competent.
Article 16.
Officials directly charged with administrative affairs of the Realm in any Land shall, as a rule, be citizens of that Land. Officials, employees, and workers in the employ of the Realm shall, if they so desire, be employed within their home Land, in so far as this is possible, and in so far as the requirements of the service or of their training are not prejudiced.
