To me that would seem to indicate an odd browser problem. The link is the link. The browser interprets what to do with it on a left or right click. Does this seem to happen only on one brand of browser (e.g., Chrome)?
Edit: Wait a minute... now I think I understand. The links are created dynamically in Javascript with the originating page followed by a hash. So left-clicking on "Terms and Conditions" goes to "T&Cs", but right clicking gets munged. In this case it seems the Javascript may be need to be tweaked.
Edit2: Likely something included from the lithium footer code (if lithium's like wordpress). I can't see anything when I look at the raw page code using Cmd-U in Firefox.
