The Base Rules as you call them are set up as follows. Each member state has to abide by the Chicago Convention and there are no differences allowed to the provisions of convention.
The Annexes to the Convention set up the base line for the Standards and Recommended Practices (SARPS), however are only applicable if a State adopts these into local Regulations - The State has to notify if they have a difference to a Standard, however not all States notify differences to recommended practices and if a State does not adopt a recommended practice it is usually up to the State to decide if they notify such as a difference or not.
The PANS do not have the same status as the Standards and Recommended Practices. PANS are approved by the Council and recommended to Contracting States for worldwide application. The PANS do not carry the status afforded to Standards therefore, do not come within the obligation imposed by Article 38 of the Convention to notify differences in the
event of non-implementation. However, the provision of Annex 15 related to the publication in their Aeronautical Information Publications of lists of significant differences between their procedures and the related ICAO procedures. Again not all States List their differences in GEN 1.7 for the PANS.
The Civil Aviation Regulations or the AIP will be the source document for States Rules. Generally the AIP ENR 1 gives an overview of the main rules applicable when operating in the airspace and list State specific requirements.
In International Airspace (over the High Seas) the provisions of Annex 2 (Rules of the Air) are applied without differences, and any difference a State has with Annex 2 is only applicable over their territorial airspace (usually up to 12 NM from the Shoreline)
Wow thanks Little. Very informative. I have some reading to do : )
