No, this is not normal. But the process_cq cheat may sometimes cause some side effects, possibly this is one of them. Make sure you've destroyed every government building present. I believe you've done this already as you can start building it, but just to mention it in case... Then try to remove it from the queue and let a turn pass, and finally try to build it again. If it never completes, you could use the process_cq cheat again to make it happen, I think.
