The recently published report of the All Wales Convention has recommended that we should move rapidly to propose in a referendum that the National Assembly has primary law making powers over all devolved matters.

This proposal should be enthusiastically supported by all – primarily because it will hardly make a jot of difference to the capacity of Government in Wales to make a difference to the lives we lead and the public services we get.

Governments have a range of tools to achieve their policy objectives. They make budgets: deciding which programmes of health, education, environmental management and transport will best meet our needs, deciding who gets what and how much. They employ people and issue contracts to implement those programmes. Government is a profoundly political process as it prioritises competing interests and tries to engage citizens in making its programmes more effective. Government is devilishly complex administrative process in which so many policies falter though inadequately designed implementation.

The tool that is rarely necessary for devolved Governments in Wales is the power to make new laws. Think back over the past decade and try to identify one significant policy that was not implemented because of a lack of legal powers. I can’t. As with all Governments, there may have been a lack of imagination, a lack of will, an inability to engage and convince citizens, a lack of resources, an inadequate administrative capacity – but so rarely has there been a lack of legislative powers to achieve an identified purpose

Significantly the Jones Parry Report assumes that legislative powers are important and references a lot of lawyers who say that is so; but no evidence is given. So why is the argument over the location of legislative powers, objectively irrelevant, so significant for some parts of our political elite?

Westminster parliamentarians have long been led into the belief that their role in making laws is important and that should it be lost then something significant has happened to the British Constitution. But look at the Bills in last week’s Queen’s speech – proposed laws which would require Governments to seek more equality, budget more prudently and provide better schools. These are things that Governments should just do; the proposed bills are entirely totemic and any enthusiasm for preventing the devolution of such law making powers is a mere fetish. If MPs made less law they might be better able to challenge the executive action of Governments in waging wars, regulating bankers, implementing fair taxes and benefits.

There are ‘devo enthusiasts’ for whom primary law making powers have acquired the same totemic status. For many such people the complex realities of actual government and politics are too messy to grapple with; far better to imagine, like a John Lennon song, a world in which legal competence somehow resolves every tension and achieves every purpose .

Let’s get on and devolve primary law making powers so that there is clarity of responsibility and no more lame excuses.  Hopefully once a Welsh Assembly has more complete legislative powers then a Welsh Assembly Government will decide to legislate less and achieve more.
