Could you be more specific? Nationality provides a legal protection in States of law to national people and access to some public services while human rights are supposed to insure a minimum universal and global protection to all human beings no matter what their nationality is. If national law targets foreigners with specific discremination measures, it would be probably against human rights but on the other hand if national law doesn't authorize foreigners to get access to all the same public services than nationals, there isn't a violation if basic rights of foreigners - as describes in human rights - are respected by public authorities. Do you have some case/example in mind about your question?
You need to distinguish between a person's "nationality" and their "citizenship(s)". You have one, and ONLY one nationality. This is with the country you were born in. I am a British national. You may have more than one citizenship. These can be attained through a process of "naturalization". I am a Canadian citizen by naturalization. I, therefore, have two citizenships: British and Canadian.
But, nationality does NOT guarantee that you have citizenship in the country of your birth. I was not a UK CITIZEN when I was born or for several years after. Rather, I was a British Subject. Meaning I was a subject of the Monarch and HER loyal government in parliament! There's been suggestions that Trump would like to deny American citizenship to the children of illegal immigrants born in the US.
So, you can not deny nationality, but you can deny citizenship. Under international law, you can recind citizenship PROVIDED the individual has another citizenship to fall back on. Under the British interpretation of that requirement, the individual need not have yet claimed that other citizenship, they just need to be entitled to it. Hence individuals who joined IS are currently being stripped of their British citizenship on the grounds that they have, OR may claim another citizenship. That entitlement will come from the nationality of the individual's parents.
Oh, so the "dispossession" of my nationality is impossible (call it a human rights abuse, if you want! But there's no need). The "dispossession" of citizenship is possible and NOT a violation of anyone's rights, PROVIDED you have a right to another. Then, there's no right to violate.
Sorry, but things are a bit sloppy at the end of my first answer. "The CLAIM (not entitlement) will be grounded in the citizenship (not nationality) of the individual's parents.
So these will be the countries of origin of the parents of which they will also be nationals.
