A federal lawsuit filed Tuesday says that Lone Star College's system for electing its Board of Trustees discriminates against minority citizens, The Houston Chronicle  reported. Lone Star has at-large elections where the entire community college district's area is used to elect all board members for the community college system. The suit argues that no Hispanic trustees and very few black trustees have ever been elected, even though 30 percent of the district population is Latino and 16 percent is black. Subdividing the system district into areas would probably result in a more diverse board, the suit says. Lone Star officials said that they had not been formally served with papers, and could not comment on the suit.
