"hat in heaven's name does this have to do with the Fundamental Law? "
You are so naive 
Kiryll took about Fundamental Law connect with non-equal marriage only early 1930.
His action against Romanovs was foolish behavior.
"Oh, and the Cheka? "
We know today that Chekaa have a strong influence in Vladimirovich family.
I will warn you once about this - do not make personal remarks to me or anyone else. You are welcome to disagree with anyone's opinions. All I asked you was what your point was - and instead of answering me, you try to insult me,
I am also warning you not to post snide accusations about the Vladimirovichi without any substantiation. It is irresponsible on a scholarly level and reprehensible on a personal level.
