"Bolton gave Tucson, also a plaintiff in the Escobar case, two weeks to file a written argument telling her why she should not also dismiss its claim. The city has claimed that Senate Bill 1070 usurps local police authority to determine how its resources should be allocated, violates the Constitutional rights of individuals who are detained and imposes a heavy financial burden on the city."

This is very significant. Tucson and I believe Chicanos por la Causa piggybacked their suits on the Escobar case. If they can't provide what the judge has asked for to her satisfaction, the City of Tucson is also out on their ear too.
