Yes... I see that.... what I'm asking is why can't the CAA consult on offering SVFR in CTAs as well (if SERA doesn't forbid it.... in which case presumably it's allowed?)
The CAA are being whipped into line as the current variation is not actually allowed for in SERA (nor ICAO for that matter). What makes you think they'd be permitted another one that doesn't?

(not being awkward... just trying to understand the issues.....)
It doesn't allow the non-separation of SVFR from IFR, and that is not is what is being proposed by the CAA, so the question is moot.
SERA.8005 (b) 'Clearances issued by air traffic control shall provide separation: ...
(4) between IFR flights and special VFR flights
(5) between special VFR flights unless otherwise prescribed by the competent authority
The CAA would be exercising the option already provided for in SERA; so technically it would be compliant. The current variation via ORS41302 and its predecessor are not in accordance with SERA.
The bit that links the VFR rules and the ATC separation rules is 5005 (h), specifically (3) 'when operated as special VFR flights'.
@Buzz53 In answer to your question, you can't, according to the rules as would be wrote, so you have to be either Germanic in your interpretation, or go round the long way.
