The troubling legal and political uncertainty facing Catalonia

There is still no end in sight to the political uncertainty in Catalonia. As Javier García Oliva writes, the issue has raised questions over processes of constitutional reform in Spain. He highlights that constitutional systems tend to make amendments difficult precisely to avoid short-term political winds driving the state in directions which may be damaging to minority interests. But while constitutions should not be carried away by every political tide and current, where there is a tidal wave of opinion, they need to move and accommodate or they risk being swept away.
