Jeppesen are merely a collator and distributor of aeronautical data gathered at (often) minimal expense from national (State) documents. That they sometimes reformat and thereby induce errors is a concern to most reputable State regulators but there is little that can be done to regulate them directly.
To answer the OP's conundrum: the ICAO SARPS (as detailed in the various Annexes and PANS) are translated into the State regulations (rules) and differences notified to the international community and ICAO by advice to ICAO in accordance with Article 38 of the Convention and noted in the State AIP.
