It is possible that basic human rights can come into conflict with each other. For example the right to a family life can be brought into conflict with the right of freedom of speech, if those using the freedom of speech right are using it to organise a riot where they are burning down houses. One has to give and it's only right that the one that gives is the one which doesn't cause actual harm to other people. Privacy and freedom of speech can come into conflict as well as has been demonstrated with the recent tabloid scandals. It is less clear cut which should give way in these situations.
