I'm struggling to know where even start to here. The two Acts you mention
are the basis for competition law in the UK, but Brexit must have passed you by, i.e.
§60 of the Competition Act 1998 was revoked [UK National Archives updated version of the Act] by it's
accompanying EU Exit regulation when the UK left the EU. So ignore EU law in the UK outside of Northern Ireland, and how the Northern Ireland Protocol dictates EU law applies.
You've quoted a
Wikipedia article that has not been updated, which is evident by it referring to §60 of the 1998 Act which no longer exists.
I know very little about the FTC process or law but I know 100% that is has no basis in law in the EU or UK. This is why I am only commenting on EU and UK legislation. You've mixing them all together as though they are equivalent, which they aren't.
And here you go off the reservation because one company raising prices is not a matter for the regulators. Prices of certain commodities, like energy, telecoms and water, are regulated by utility regulators, not market competition regulators. What you are posting is irrelevant. If one company (Sony), in a competitive market, puts prices up then the market (consumers) will decide whether those prices are fair - that is the literal definition of a free market. It is absolutely not a matter for the competition regulator.
The EU and UK CMA processes do not require going to court. My understanding of the FTC profess is that they
have too, because US regulation is implemented as a legal process (the FTC is part of the judiciary, no?). The norm for regulation in both the EU and the UK is that regulation is a matter for civil authorities, but these authorities still have the legal powers to control, approve, deny acquisitions as well as prevent trading and seizure of assets. As I said above, you don't seem to be aware that the UK/EU processes are very different to the US process yet both the EU and UK CMA can require disclosure of documents (which the CMA have published in redacted form).
Please stop pasting walls of text, it's clear you're not understanding what you're posting.
