In America and Britain, the world’s core democracies, the legislatures, Congress and Parliament, are the weak link in the system of governance and in danger of marginalising themselves towards irrelevance.

We the people elect lawmakers to make important decisions on our behalf. An executive is constituted to collaborate with the legislature in the preparation of policies and to put into effect the lawmakers’ decisions. Among several reasons for this double structure of governance is that it increases the likelihood that decisions are well prepared and that governance will be effective. That’s part of the case for democracy.

Dictatorships do not have a similar double structure. There the making of law and the implementation of law is in the same hands. That increases the risk not only of despotic policies, but also of badly prepared decisions slipping through because there is not enough scrutiny in the process.

A problem with the democratic double structure is that there tends to be a tug of war between the legislature and the executive about who should do what. The executive invariably wants to dominate. If that is allowed to happen, the benefit of double structure scrutiny may go lost and democracy pervert towards de facto dictatorship. It falls on the legislature to stand up to the executive’s inclination to dictate.

In Britain, the tug of war has become visible in the preparation for Brexit. The government initially insisted that it should be in charge (by “royal prerogative”) with little or no involvement of Parliament until the government had negotiated a new deal with the European Union. However, that attempt by the government to claim for itself powers that belong to Parliament, failed when the Supreme Court ruled that the government did not have the authority to trigger Brexit without a formal decision by Parliament.

However, the remarkable thing in this process was that Parliament itself was unable to stand up to the government’s assault. We had the undignified spectacle of individual MPs appearing on the evening news and demanding that the government involved Parliament, while Parliament itself had no voice in the matter. Only when a private citizen brought the matter before the courts, could they lay down the government’s duty to collaborate with Parliament.

The government responded with issuing a Brexit Bill, as it then had to, but continued the battle for dominance. The Bill is only 130 words long, with no detail, and Parliament was given only five days to deal with it. Again, the spectacle of individual MPs popping up to complain and demanding that the government gives them more time. But Parliament itself has no voice in deciding on its own procedure.

In America, Donald Trump was inaugurated into the presidency and set about issuing a flurry of “executive orders” with wide reaching consequences. In so doing, he was claiming for himself the authority (the American version of “prerogative”) to make new law without involving Congress. This turned into a case study in the risks inherent in decision making without scrutiny. One sweeping order suspended entry into the country of all refugees for 120 days, of Syrian refugees indefinitely, and of all citizens of seven predominantly Muslim countries for 90 days. This was a manifestly bad decision, with unforeseen consequences galore and bringing global condemnation down upon America, a result of the decision having been badly prepared or not prepared at all. It was also a despotic decision, setting aside established American law in the matters concerned.

The order on refugees was brought before the courts by civic groups and immediately set aside as unlawful, at least in part. The remarkable thing, however, as with Parliament in Britain, was that Congress itself had nothing to say about the executive’s usurpation of legislative power. Some members of Congress grumbled but Congress itself said nothing.

At the time of writing, the outcome of these tugs of war is unknown. Meanwhile, the respective governments come under criticism for being power hungry and ruling autocratically. That criticism is valid, but superficial. The executive will, if it can, grab power. It is for the legislature to prevent it. In both America and Britain, the weak link in the system of governance is a legislature, Congress and Parliament respectively, that does not assert itself and fails to do its constitutional job. It is when the legislature fails that democracy can pervert towards elective dictatorship.
