That’s interesting, Red.
To extrapolate, the government would presumably have no choice other than repeated lockdowns in order to prove that they had done everything possible not to put those lives at risk?
You have the argument about what is 'reasonable' to contend with.
What is a reasonable expectation of mitigating risk and at what point are you discrimating on the basis of age and disability?
A general private citizen might struggle to argue how far the government is obliged to go to 'reasonably' protect them in a national crisis.
But its not that straightforward and there are situations where it is more clear cut and the legal bar is higher.
People in state care are under state protection - the state are directly responsible for them in a way that other citizens dont have. So the bar of legal protection is higher than for the general population. Their right to life is enshrined to a higher degree of proof and a demonstration of taking measures to protect them especially because they are vulnerable and not able to take steps to do this on their own.
Thus protecting well residents against a known threat (a covid positive patient) or a high known risk (a patient who is at high risk of being covid positive as they have been in hospital but hasnt been tested) is a clear health and safety matter for which there is a set of protocols which should be adhered to.
For the wider public this set of rules isnt quite so clear cut in terms of who is responsible for every situation.
But if for example we got to a point where the level of infections were extremely high and we started having hundreds of teachers dying because they were prohibited from wearing masks in the work place you might have a problem. You could legitimately argue that since the government had previously shut schools and other work places had masks as part of basic health and safety that teachers had a reasonable level of expectation that schools would shut again if the level of risk became too high.
So the answer is that the government do not have to legally keep putting in restrictions, but its simultaneously does have particular legal responsibilities in certain situations which are clearly set out in law.
This may be one reason that the government is keen to get rid of human rights law going forward though too. (lots about cutting red tape etc in the newspapers in relation to brexit atm. But it also has serious implications with the ongoing covid crisis too)
To further confuse the issue I will add though that the government does have the legal ability (particularly with the covid act and the civil contingency act and the size of the government's majority) to suspend these legal responsibilities anyway. They could unilaterally without parliamentary scrutiny remove health and safety law. But it does get more complex because of how human rights law works - under your right to life.
This would be a) highly controversial and b) at present the uk government is still answerable to a higher court of law - the ECHR (note any moves to end this which are currently in progress) so if the government did remove responsibility under uk law they could still be taken to court (most likely by one of the devolved governments i suspect).
So i would strongly recommend people watch what happens with brexit talks in relation to this area of rights. The Withdrawal Agreement enshrined our willingness to continue to adhere to and to be answerable to the ECHR. No deal leaves us extremely vulnerable to the whims of this government and who they value pritecting and who they don’t.
Sorry thats not a more straightforward and simply and non political answer.
