According to Spiridovitch, the report was requested by Nicholas II soon after her conversion. Tchetcheglovitov, the Minister of Justice, sent the report to Nicholas II as well as Maria Pavlovna. There may well be a copy tucked away in GARF somewhere. It was clear according to him that the law required dynasts to be born to an Orthodox mother. As Maria Pavlovna was NOT Orthodox, her children could not inherit the throne. Further, when Alexander II gave permission for Vladimir to marry a non Orthodox, his ukaze very interestingly said only that Vladimir did not lose his succession right, but there was no mention of his children's rights. Don't confuse the rights and privileges that came with being the grandsons of an Emperor with being able to succeed to the Throne. According to Spiridovitch, Nicholas II himself was convinced that Vladimir's sons could not succeed to the Throne.
