The Justice Department announced Wednesday it has filed a civil lawsuit against Tinley Park, a town of roughly 58,000 to the southwest of Chicago, for refusing to approve a low-income housing development.

According to the lawsuit, the Buckeye Community Hope Foundation sought to build an apartment complex for low-income people nearby Tinley Park’s downtown in 2015. It would have been financed through Low Income Housing Tax Credits given by the Illinois Housing and Development Authority.
