Can this help my case any if I did not refuse the signature?
Interesting question, which, if I understand it, is: Are you required to sign the 20-16.2 rights form?
The answer is: Not necessarily.
The legal issue(s) probably would boil down to whether the rights were actually read and whether a copy of the same provided to the accused.
Normally a signature indicates or at least suggests proper process was filed, rights were advised, and a person understood those rights.
Indeed, there are times when people can't or just won't sign.
That doesn't necessarily require suppression of the breath test; nor would that cause an automatic dismissal of the charges.
More information would be helpful, which probably would be best shared PRIVATELY with an attorney.
Many criminal defense lawyers provide a confidential consultation, free of charge.
Really good question though!
