What documents will the court accept when priors are being used for acca enchanment

[sweetblack29]

Hello this is a repost with a few more details. So my man is trying to appeal a few things. The one thing that we are stump on is the type of document that the court will accept when enhancing a prior. He said that the procecutors never used his transcripts for two of his priors so I have a list of questions, if im unclear please excuse me . How does a lawyer prove that a person priors qualifies for an enhancemnt (acca) . Are certified records needed to convict priors as an acca if so what kind. How long can you use a prior in the state of mass. and finally what does it mean when the gov. must formally file a bill of information with the court either prior to the trial or guilty plea, what is the bill and what does it entitle.Thank you for reading and trying to help me with my issue google and ask.com is driving me in circles lol Thanking you in advance
