Yes it is legal to autopen. President Bush had Rumsfeld autopen sorry letters to parents whose kids died in Iraq UNTIL Americans made a stink about it. Of course nobody is making a stink about Obama using the Autopen....come to think about it, Americans don’t cause a stink about Obama on anything.
Sorry letters are not official documents.
This is an official document which is law. Is it legal to auto-pen a document such as this?
