infringement of sovereign prerogatives

Under the Constitution of the Empire of Japan, infringement of the sovereign prerogatives was considered a serious unconstitutional act.
Compound of 大権 (たいけん, 'supreme authority, sovereign power') and 干犯 (かんぱん, 'violation, infringement'). The term is closely associated with the Meiji Constitution era.
