The Cubs didn't care until the rooftop owners began meddling and held up the building permit when they first started planning the bleacher expansion, as they were afraid the expansion would interfere with their views, and hence, their profits. The rooftop owners brought it on themselves. Exactly. Also, while thats the rooftop owner's property, Wrigley and what goes on inside it belongs to the Cubs and they have every right to block that view if they want to (barring any crazy Chicago zoning laws that I don't know about). It's like complaining about me putting up curtains in my house because I don't want nosy neighbors looking in. Yeah, I agree. The Cubs absolutely have the right to modify their property to block a view. However, if the Cubs choose NOT to block the view then the neighbors are still entitled to enjoy the view from the property as they see fit. Unless there is an agreement in place that they would pay. Depends on the legal status of the agreement. Was it just a handshake deal, or was there a legally binding contract? If so, were there penalties stipulated in the event of a breach of the terms? If it was only a handshake deal then people are entitled to reconsider it. It doesn't really depend on the legal status of the agreement. Let's say it was a handshake agreement. The Cubs aren't talking about legal recourses. If the owner doesn't want to pay up, that's fine. The Trib is exercising it's right in either case to erect an obstruction. Even if it was a verbal agreement (that the Cubs alter their bleacher plans and take down the shades in 2004 in exchange for 17%), and that rooftop owner was witnessed by others as agreeing to it, it can still be enforced in court as well. Let's say that the agreement was made by all of the rooftop owners but that one. The Trib obviously still has the right to block them if they want. Either way you look at it, the rooftop owner has no legitimate complaint whatsoever if his rooftops get blocked.
