Currently it looks like the FIA don't have a leg to stand on since an in house legal team said "Yeah, that's cool" to Mercedes. If they don't get reprimanded and the loop-hole is closed, will other teams feel hard done by? Most likely.
Personally I think Mercedes did nothing wrong technically, although it was treading a fine line but when it comes down to it, Pirelli arranged the test, ran the test and collected the data. The only way they could really put it beyond doubt is if Pirelli ran it's own test drivers instead of Mercedes using Hamilton and Rosberg.
[This turned into extreme blame everyone but Mercedes exercise. Pirelli. FIA, Whiting. What's going on?] In a word: what

FIA no legal leg to stand on? On the contrary. Unsanctioned by FIA test with an F1 2013 car happened, physically.
This "loophole" of who conducted test is a really weak one, even if it was FIA who noticed ambiguity, and even if you ignore all other requirements to conduct such test. Legally it means little or nothing. As already pointed out those two lines of defence (second: Ferrari test) were presented in order to plead for leniency and create better image. We did it but without bad intentions, even your highest authorities were aware of some "possibilities", we discussed it etc., that's a good argument but not strictly legal one, it's more about circumstances.
You can't say Mercedes did nothing wrong technically, on the contrary technically they did everything wrong. Phone call from Whiting is not legally binding even if usually it works like that (DDRS)

. You can't just say it was only Pirelli test, again: involvement of F1 team's cars, drivers and engineers plus some data security irregularities make it also a Mercedes test. You can't test with 2013 car, they did, end of story, the leg to stand on but not Mercedes'.
Their main defence point is based on the assumption that real life gains for the team are negligible or don't exist. Are they? I have no idea, apart from some noise from Red Bull and Sauber how everything can be useful and Rosberg knowing what tyres they used I didn't see attempts to quantify those gains. And why the circus with helmets?
I also can't make a judgement about this test because I don't understand the part about FIA's and Mercedes' involvement. IMO possible penalty should be based on whether or not and how much Mercedes really gained from it. Forget legality, if there wasn't any gain (100% certainty) no real penalty. But if there was even as a possibility or difficult to asses than maximum theoretical gain should be the reference point for punishment.
