They could send an automatically generated mail saying:

We had to suspend your account because you violated rule X (link to description). To have your account reinstated please do Y or Z so you are not in violation of X.

Simple, isn't it?

That is simple, but Google explicitly states that they will not do that. Instead, Google linked to:

https://www.google.com/adsense/support/bin/answer.py?answer=...

Which states:

"Why was my account disabled? Can you tell me more about the invalid click activity you detected?

Because we have a need to protect our proprietary detection system, we're unable to provide our publishers with any information about their account activity, including any web pages, users, or third-party services that may have been involved. "

So, you may submit more information to Google, but Google will not submit any more information to you. Thus, there is no need to entertain a discussion regarding your account ---at the expense of both parties--- as Google will not submit any further information to you.

That's reasonable to me.
