I am currently finishing the 'Modern Dynastic Rule' article for the Oxford University Press (online bibiliography series) with a little under a hundred (annotated) sources, that should come out by the end of the year (depending on the editorial process).  This will provide you with everything you need.  I hope you do consult it.

Dear Farhad,

thank you very much for this reference. I followed the progress of the case, even since Mr. Kirkhope started it, but the address you linked collects all the top stories.

Dear Mr. Yates,

I will eagarly await your publication. This is great news! Would you give us some details concerning the place of publication i.e. will it be a book or an article in a scientific journal? (what title). In September, my book will be released on the monarchical principle in modern mixed monarchies of the world (Gdansk University Press). About 500 pages of text. Unfortunately only in Polish language, but maybe I will be able to translate it and publish in English.

OPU online bibliographies is the publication for my 'article' (finishing now) but my 'book' on ten modern dynastic republics is not yet finished.  Thanks

To my perception please find very impressive and comprehensive work by Lucas Prakke Swamping the Lords, Packing the Court, Sacking the King European Constitutional Law Review 2006. It is the really glorious article about three genuine constitutional crisis and at this very issue Belgium constitutional dilemma stemmed from King's conscience to refuse the promulgation of the abortion bill. As an author indicated "King handed Prime Minister Martens a letter in which he stated that he was prevented by his conscience from sanctioning this law". As Prakke argued finally the victory of democracy in each indicated case was visible but the genuine perception of each case uniqueness and particularly the Belgium one I truly hope help you strongly.
