The legal situation was tangled. The law forbade starship departures without commission approval. Approval was hard to get and slow in coming. Zerchi was certain that the ZDI and the commission would consider the Church was breaking the law. But a State-Church concordat had existed for a century and a half now; it clearly exempted the Church from licensing procedures, and it guaranteed to the Church the right to send missions to "whatever space installations and/or planetary outposts shall not have been declared by the aforesaid Commission to be ecologically critical or closed to unregulated enterprise." Every installation in the solar system was "ecologically critical" and "closed" at the time of the concordat, but the concordat further asserted the Church’s right to "own space vessels and travel unrestricted to open installations or outposts." The concordat was very old. It had been signed in the days when the Berkstrun starship drive was only a dream in the wide imagination of some who thought that interstellar travel would open up the universe to an unrestricted outflow of population.
