Not really, because the US legal system is completely different to the Commonwealth legal system. The US legal system is open to interpretation, it allows a lot of weight placed on precedence, it also basically allows a jury to decide in civil cases.
I've got a lot of respect for many of your posts in this thread, however, this is one so far off base in respect of the laws of England & Wales that I'm not even sure where to start.
The legal systems in England and the USA are both common law systems, and thus are nowhere near as far removed from each other as you suggest. The English legal system was exported in some form to nearly every country that the British Empire touched. Obviously, over time, they will diverge - and countries which became independent from Britain much longer ago will have diverged more than those who only got independence more recently. But the fact remains that the US still operates a variant of a common law system, and some could argue that your courts at a Federal level are actually MORE restricted in what they can do than a court in England.
Judges in England regularly interpret legislation. There are actually a range (and tiers) of methods used by judges to understand the will of parliament in passing that law. We also have the fun interaction of legislation and precedent from Europe (the EU and ECHR/ECtHR). The result of this situation is that court decisions often go against what parliament and the public would consider to be the 'right' situation.
The only point there I agree with is on juries - you are right that 99% of civil cases in England don't have a jury.
I will also say that "commonwealth law" isn't a term I've ever heard anyone use here in the UK (as a way to describe a collection of legal systems), and I'm almost certain you're referring to "common law systems".
Commonwealth law does not work that way, and you MUST physically have proven all the proofs associated to a specific existing law, regardless of precedence, regardless of who has the best spin on things. If you cannot associate an actual law or ruling associated to the law (the only precedence acceptable), then you're screwed.
Sorry, wrong again. In theory, to an extent yes. In practice, no. There are various ways to win in court without a strong legal foundation. You may also wish to look at the English concept of equity (I understand this also exists in the USA), which is all about bending the law when it's going to give the "wrong decision".
Commonwealth legal is not open to interpretation in civil matters. This is why IB had to put into escrow an enormous sum of money just to have that case sitting, awaiting, because Commonwealth law is not easy in civil proceedings.
Wrong. They had to deposit that money because IB had no assets left in the UK - thus if XF won, they wouldn't be able to reclaim their costs. This is one of the great benefits of the UK system - if you sue someone and lose, you're nearly always going to end up paying for their legal costs.
You can't just go around suing people in Commonwealth law because of accidents or incidents. If someone is at fault in a civil proceeding, courts don't issue ridiculous rewards to the other party, unlike the US courts do. There is no millions of dollars for being in a car accident, slipping in a shopping centre or such, not under Commonwealth laws.
Sorry, wrong again. While not as bad as the USA admittedly, we've got a horrible "compensation culture" here in the UK. Our government is currently legislating to reduce some of that (particularly around car accidents).
You would likely offend a British court just by raising what happened in a US court... they literally wouldn't care and any judgement by a US court would have near zero weight on the Commonwealth system.
No, you wouldn't. It's quite common to try to enforce a judgement from a foreign country and court in a different jurisdiction (this is a perfect example with IB in the USA and XF in the UK). English courts are quite fond of their American counterparts. A law firm has helpfully provided a summary:
