@engineer,
I thought it was odd that Catholic agencies will place children with people who are single, but not to a person who claims to be in a civil union. It seems that as long as applicants do not declare that they are in a same-gender relationship, the agency will place a child with them.
In the Illinois court case, the judge is being asked to balance freedom from discrimination for civil union partners with the "freedom of conscience" that Catholic officials seem to be asserting.
