Three of my close relatives entered into an "oral" agreement to run a park-like (open space) locaiton in support of a new and varied food cart operation (many carts). They were asked to secure a liquor license for this area, which they did. They are also are putting their own food cart in this area. Upon securing the license the owners told them that they changed their mind and are hiring a "promoter" to run this open-air area.
Question: Do they have any legal right to pursue this in the civi court?
