On the IARU-R1 site he writes:
In a collaboration between the IARU-R1 Spectrum and Regulatory Liaison Committee (SRLC) and the Political Relations Committee (PRC) an IARU Region 1 response has been provided to the European Union consultation on the WRC23 agenda items.
All the agenda items of interest to the IARU are covered with particular attention paid to the AI9.1b issue on the GALILEO / 23cm band amateur service coexistence. This is an important messaging activity and the IARU response again underlines the IARU view that with only two cases of interference recorded globally, the potential for interference is being over-stated and that any regulatory solutions should be proportionate, realistic and appropriate and should not hinder the future development of amateur services. The IARU would be pleased if member societies could share these same views with their national regulators.

The PRC/SRLC is also developing a response to the European Commission Radio Spectrum Policy Group (RSPG) on the same topics.
Secondly the CEPT project team SE40 that is carrying out the CEPT studies on the RNSS/23cm band topic met during the week 25 – 28th July 2022. The IARU provided a contribution and participated in the meeting supported by USKA. Good progress was made but further work continues to be required to finalise the conclusions from the studies. The IARU continues to be concerned about the lack of consideration being given to the low probability of interference and more work is needed on this aspect. A summary report can be found at
