My thought process for AE appeals which arrive at the Committee is pretty straight-forward. We (ArbCom) are at the end of the appeals process for AE sanctions, similar to case requests. Therefore, my considerations are twofold: (a) where processes followed in the application of the sanction and in any subsequent appeals and (b) was the sanction imposed a reasonable exercise of administrative discretion. In this instance the answer to both questions is yes, so I !vote to decline this appeal request and recommend it that be taken to the admin who originally imposed the sanction or to WP:AE.
On the topic of having a limit to the amount of time page protections (and other sanctions on pages) can be placed I'm not convinced that's a good way forward. Firstly, blocks are more contentious and have a great affect on people than other sanctions and are, generally, more difficult to lift. Secondly, administrators aren't authorised to impose some page sanctions (such as, 1RR and 'consensus required') allowed by discretionary sanctions so having them expire after a year would mean that they expire (not that it changes to allow any admin to remove them). I'd also imagine that the imposing admin, AE admins and editors at AN would be very willing to amend/lift page restrictions which have been in place for long periods of time (especially when compared to blocks).
