Did you read the last item on HART's list:

"Exposure to Lawsuits from Developers and Investors with Developments Near the Rail Alignment".

Wait .. what?  Why would they have any standing to sue the City?  Did the City promise them that Rail would be built at any cost and put it in writing. or maybe a legally binding wink-wink?  The developers didn't contribute to the construction costs.  Yeah, if Rail dies those Kakaako monuments get devalued overnight, but that was the risk they took in building them.  Booo-hoooo.
