Legal Question in Criminal Law in Texas

Can a Judge's Decision from One....

You've not really included enough information here to answer, and in many states the "county" a judge is from is less important that the "Circuit" the judge handles, perhaps including several counties. The question is going to turn on the laws in your state -- talk to an experience criminal defense attorney there and they will almost certainly know.

Can one judge change a bond

Since the message seems to originate from TX, I feel I can answer it. If it is NOT from TX, this is not a binding legal advise as I am not licenses anywhere but TX< CO and USVI. In texas USUALLY only the judge setting the original bond can change it - unless the bond was set by a County Court judge at nitial advisement and the case, on indictment went to a district court and the DA made a motion to declare the bond insufficient. Then it can be reset. The other way would be if the bond was surrendered or forfeited then, when the deft is rearrested a new and higher bond can, and probably will, be set. Of course, at any time, a DA can petition the court having jurisdiction EX PARTE to have the bond ruled insufficient and require a new, higher bond required. I had this happen recently with a client who had his bond raised EXPERTE when he was arrested for a new felony offense - when he was found NG of the new offense, I was able to get the original bond restored.
