"mmmm which i why i used "perhaps and could" so no, i have to disagree, you ve just chosen to interpret it this way."
On the contrary, you attempted to make a clear link between JSO and Unions. And failed in the process.
"Laws can of course be changed, like i said, had the Tories won, strike action by Doc's/Nurses could then become unlawful (subject to min services levels) and they could then find themselves branded "extremists" and sentenced according to the law."
Laws that don't evolve to deal with emergent threats which are novel is a bad idea. That laws can be evolved, amended or altered is not an argument in favour of keeping laws in a straitjacket permanently.
Society doesn't stand still and neither does various threats to the society itself.
"In the case of JSO, had they done the exact same protest a few years ago, they would not have been sentenced to 4/5 years."
I suggest you read the judge's own ruling on this instead. It provides clarity on the legal reasons.
"Just because the law says so, doesn't automatically make that law just or correct, history is littered with examples."
This is simply Circular Reasoning. In other words, you've put the cart before the horse. Do yourself a favour and read the actual ruling itself.
Including the bit where previous criminal record by the accused was taken into account which results in....longer sentences imposed.
