Some people are trying to destroy Britain

Exactly, Parliament has all the power  

Oh do fuck off with your endless attacks based on nothing but fuckwittery

I already explained that I knew about those things because I'm married to someone who was a senior civil servant who had at times to say no to ministers.  I then gave public references of provenance that backed me up- yes I had to google those but I started from knowing the facts.

That you wish to live your life in sad denial of the truth endlessly throwing out abuse at those who try to show you facts is a tragedy but one where you are the main victim and all of your own doing.
 

This is just a bland generality. If someone feels something is against the law and doesn't want to do it, unless circs are extraordinary, they are free to resign and not do it.

Well that presupposes that they know it is definitively against the law their choices are clear if they believe it is illegal. They would only get their job back if it was actually shown to be an illegal request. In many cases the law is not clear cut.
 

So the issue is what if the minister of the crown orders something against the law.

I practice often it is done (hence all the judicial reviews this government have ended up in) but it is actually the duty of the civil service to adhere to his majestys's laws. So sometimes they will obstruct the law breaking.

To take a theoretical example. Say the government passed a law saying 'no one shall restrict the colour of car anyone has' Some years later a minister calls for MOTs to be failed if a car is yellow. The Civil Servants should say "no, you have to change the law first'

You're trying to change the theoretical example for no good reason. It was only ever illustrative of a point.

Examples of problems come from the Human Rights Act, The Climate Change Act and the myriad of Finance Acts. And then there's the issue of 'enabling legislation' which allows a secretary of state to make law as and when BUT crucially only within the scope of the enabling legislation and by the processes it defines.

This government has found itself over and over on the wrong end of judicial review decisions and is now intent of preventing it being held to account by such reviews. Because at heart it believes it is above the law.

Exactly. When Boris prorogued Parliament - probably to stop Remainers trying to block Brexit - he was challenged in the Supreme Court by a Remainer cabal, and the court declared it to be illegal. The law was unclear. However according to Lord Sumption the Supremem Court had overstepped its powers in calling it illegal. He said that there was a grey area between what should be decided by the govt and what should be decided in court and that the Supreme Court had effectively moved into the area of law-making - which is outside their remit.


But the point is that the CS has to do what they're told - or they can be sacked. And if there's any doubt as to whether what the govt intends is illegal or not the govt can get the Attorney General to give his legal opinion. Laws are invariably ambiguous and the decision is NOT up to the civil service.
