ICAO does not have jurisdiction, the competent authority in each country does. And it can deviate from ICAO as it sees fit.
What is needed is a reference to the UK CAA permitting SBAS for LNAV/VNAV guidance, even for baro approaches, and even though it now has no agreement in place with the authority which provides the signal. The Open Skies principle will not suffice for this; ditto SoL, which is merely a standard anyway.
Perhaps it would be helpful if you could paste in, or at least reference, exactly the pertinent passages of the regulations you are referring to. That would prove the point and stop each ppruner scuttling off to scour the regs.
Once these NOTAMS get worked into the AIP, assuming the matter is not promptly resolved, an update of your Garmin database will simply see the SBAS option disappear for all UK airfields. That could be in about 56 days time. Or 28 if they are really snappy.
