I received an email asking this question and thought it better answer it publicly. It read:

I was surprised and delighted to see from a recent post where the poster linked to a RYA Appeal, that RYA, CAN and US Sailing Appeals are available on the website.

I can find some of these using the Find/Search facility, but can you tell me, please how to access these appeals through the menu system.

Are they or will they be linked to the rules as the WS Cases are?

You can see links to MNA appeals or decisions by selecting the appropriate Prescriptions.

Once you've selected an MNA, the related cases or appeals will be displayed in the same way regular cases are displayed. Note however, that the RYA has indicated that they will not allow RRS.org to use the RYA cases, so they are not shown when you select the RYA. The RYA decisions are only available by search.
