FYI it wasn't "the gang of four" that stopped construction for more than a year.  It was a lawsuit filed by and won by Paulette Kaleikini . Kaleikini filed her rail lawsuit against the city and state in January 2011, the same month the project’s programmatic agreement was finalized. Fast forward a year and almost nine months later, through a court appeals process and the involvement of the Hawaii Supreme Court, Kaleikini walked away with what she’d been asking for all along: a complete archaeological survey.  
The city failed to follow the law and do the Archaeological Inventory Survey on the whole project before construction began.  The city lost the lawsuit and was forced to follow the law.
So to say the "gang of four" caused the more than year delay on construction is fa false statement.
