"De jure" means "concerning law" while "de facto" means "concerning fact". A state may be de jure sovereign without being de facto sovereign, because a greater nation maintains economic or political hegemony over them, as Syria did with Lebanon. Or vice versa: de facto sovereign without being de jure sovereign, like the tribal areas of Pakistan.

The country is not stated in the question.

However, in the US, De Jure segragation no longer exists.

De jure standards are standards that have been approved by standard bodies, professional organizations, industry groups, a government body, or other groups.

De jure belli ac pacis was created in 1625.

jure power = legislation ;facto power=justice
