Did Connecticut wait too long to sue over building flaws at university law library?

From The Hartford Courant: The construction industry is asking Connecticut's Supreme Court to block the state from invoking a 13th-century legal doctrine that, the state contends, allows it to wait decades or longer before suing for defective work on public works projects. The dispute stems from multimillion-dollar leaks at the University of Connecticut's law library. The state waited until 2008 to sue over the leaks — 12 years after the building was complete. The state argues that it can sue whenever it wants under the ancient English doctrine known as “nullum tempus occurrit regi.” Individuals and businesses generally must sue for construction deficiencies within six years.
