Currently in Prison for Parole Violation and Warrant Out for Pending Charges

[DARS]

My question involves criminal law for the state of: Texas
While on parole, my friend obtained a DWI 1st offense, and 4-5 hot check charges. His parole was revoked and he is now serving time in which he will be released in March of 2013. He has recently found out that the county in Texas where he obtained the DWI 1st offense and the 4-5 hot check charges is holding a warrant for his arrest. Said county has put the prison where he is currently incarcerated on notice to detain upon release til a sheriff/deputy can pick him up to face pending charges evolving around said pending warrant. My friend would like to know if he is entitled to obtain a speedy trial in which to be sentenced on pending charges to run at the same time that he is presently serving time.

Texas is really weak on speedy trial laws. If he was in jail pending charges, he might have a right to priority, but since he's under sentence from a previous offense, that's a different story. There's no requirement that they try him while he's still in prison and there's no requirement that any judge give him sentences that overlap with the current one even if they do.
His lawyer would have to push the issue to try to get priority, but I'm not seeing it as likely.
