Even the constitution of Switzerland there is a little line they have added without asking us, which says that international law supercedes national law in the health matters.
This seems strange in two aspects. First, as far as I know, it is not possible to add lines to the Swiss constitution without a referendum. Second, the contents of such law seems contrary to the Swiss principle of democracy.
Question: is there a line in the Swiss constitution, or elsewhere in Swiss law, that implies that international law supercedes national law in health matters?
