Several comments.

RON: Adding RON gets rid of one of the selling points you made pro IRV, however - once RON is added, then any election with two candidates will not be mere FPTP as RON will be part of it as well. On the other hand, having RON for uncontested elections is a very good idea, as it can be a trigger to get people running that weren't so sure before, thereby at least spurring the debate. I'd prefer RON to only be an option in the first round of an uncontested election.

EC: While I certainly appreciate generalizing the language in EA 1.3, I fear this generalization is a bit too broad, specifically as it pertains to the cabinet. To illustrate a few of the consequences: A cabinet member could oversee the election of another cabinet member in a special election - not desirable. Furthermore, an outgoing cabinet member shouldn't oversee the election for the incoming cabinet either, which this language allows. I'd prefer if this section includes both standing for and holding the office to be elected, and ensures that cabinet members can't elect each other.

EC, the second: I really don't understand the point behind changing EA 1.4. I don't particularly mind removing the permanence, but I am strongly opposed to removing the Assembly's power to remove an EC member.

IRV: Fine with me, though I'd prefer if all acronyms are defined (FPTP is just plopped in there, for example) and the actual process explained. People shouldn't be looking it up in Wikipedia instead of our laws on the procedure.
