Spell Immunity and Divination Spells

[Dr. Johnny Fever]

If a creature has Spell Immunity (or Greater SI) cast upon them, can the caster choose to have them immune to a divination spell? Personally, I don't think they can since what Spell Immunity does is effectively gives the recipient unbeatable SR against the chosen spells, and most divination spells (See Invisible, Analyze Dweomer, etc) do not check SR.

Lol even as I'm writing this I'm convincing myself even further that I'm right. Has anybody got a good counter argument? I suspect this will come up in my WotR campaign relatively quickly (Analyze Dweomer is basically a big 'F U' to the DM's buffs on the BBEG) so I want to be able to have a cogent (and ultimately succesful :P ) debate when that moment arrives.

Spell Immunity only applies against spells that have to get past SR.

From the Core rule book and PRD
Naturally, that immunity doesn't protect a creature from spells for which spell resistance doesn't apply.

There you go. :)
