Are there any countries on earth that can legally deny its own citizens entry into said country?
I'm excluding transit to different countries to reach the destination.
It's also irrelevant to the answer on what happens after the person has entered the country (Like arrest or quarantine)
I'm specifically asking if a national of a country (holder of said countries passport) or resident of a country (with valid residence permit for said country) is standing at the border, could they legally be denied entry?
