Senator Tuffy expressed her unease about the safeguard clause. There is nothing in the legislation that provides for the expulsion of non-nationals if there is an economic downturn. However, it is prudent to be able to regulate new entrants in such circumstances. Senator Tuffy also referred to the introduction of a green card system. The case for Ireland requiring it is not proven, but the Government has an open mind. We should be able to meet most of our needs from within an enlarged European Union. In debating issues of this kind we sometimes tend to forget that Ireland is a member state.
