Non-elected ministers

As is the case, for example, in the US, in France and Germany, the Executive (Cabinet) is not formed only from elected persons. In France and in Holland, persons appointed as ministers are required to leave parliament.
In the Westminster (British) system all ministers have to be members of Parliament or of the Upper House, the Lords. Same in Australia, Canada, NZ, India, Ireland etc. The South African Constitution provides that the President may select no more than two ministers from outside the Assembly - these ministers have the same relationship with parliament as other Cabinet ministers.
So it is here in Mauritius  that all ministers have to be appointed from members of Parliament, with the exception of the Attorney General who can be anyone qualified in law.
This exception (for 1 non-elected minister) should be broadened to allow the inclusion of a number of ministers (3? 5? more?) chosen from outside Parliament, from top-level professionals in their respective fields. Especially so for technical ministries such as tertiary education, agriculture, transport, energy, industry, tourism, environment and even economics and finance. Not that these ministers must necessarily come from outside but such amendment will allow the PM/President the choice and freedom to construct the best, highest level cabinet-team that can be had, Parliament retaining its essentially legislative function.
Top-level competence, Singapore style, is essential today and surely in the coming years, at the highest level of governance (at policy/strategy/ decision-making levels) which will be determinant in the survival and success of any state, especially of course small isolated island states like ours. Destructive incompetence, or else insignificant rate of progress and development, as quite a few ministers have shown since independence, must in any case be something of the past. If you can't do it you have no right to be there!
For a lean and strong government, ministers need to be professionally appointed based on their expertise and experience. The appointment of Ministers from outside Parliament enables the choice of better and capable persons to hold the office of Minister instead of relying ONLY on elected members of Parliament who may sometimes non-professionals, career politicians. Such non-parliamentary ministers will have more time and energy to concentrate on running the government instead of worrying about matters of constituency.
We are, in Mauritius, in many instances, still at the primitive level of choosing ministers (especially in a Government with a slim majority) for their ethnic, class, caste or socio-cultural appurtenances. Ditto for heads of some para-statal bodies, Commissions etc.
As we prepare to vote constitutional amendments to the electoral system, the above amendment to allow specialist non-elected ministers would be an additional move forward for Mauritius.
