Dallas County Commissioners and their juvenile department are set to go to court following months of tension over access to records that could show if children at the county detention center are kept in isolation for most of the day. An initial hearing is scheduled for July 26 at 10 a.m. in Civil District Judge Eric Moyé's courtroom, where he will decide if county commissioners can receive subpoenaed records from the Dallas County Juvenile Department, according to court filings.
