What is the name of your state (only U.S. law)? New Mexico
Is a Doctors note a legal entity? Can you be charged for forgery
What say we stop goofing around and get to the story all in one thread, hmmm?
You forged a doctor's note and the principal called the doctor and, surprise, there was no doctor's visit and the doctor refused to lie for you.
Yes, it was legal for the principal to call the doctor. Yes, it was illegal for you to forge the note. No, the odds against anyone actually calling the police are huge.
In other words, the long and the short of your punishment is whatever the principal and your parents dish out.
