The parking and road existed as public access before Vinod bought the house. The argument is where something that was public before can be made private without prior approval.
Public != Free
Public != Free
Yes, it's my understanding that Khosla owns the entire compound and all of the houses. It's one property and was operated as a business by the former owners, the Deeney family.
The previous court case that (SCOTUS declined to hear) was really about whether Khosla needs to apply for a permit for his development work that changes public access to his property. SCOTUS declining to hear the case essentially means that Khosla needs to apply for the permit for these changes -- the implication is that until this happens, the case is not actually ripe for review. If he's unable to obtain the permit, then Khosla may be able to pursue his argument that the state's mandated public access is an unconstitutional "taking" of private property. (IANAL)
It seems if he had been more careful with his approach he could have kept the beach clear during winter just like the previous owner did without any legal hassles.
Still doesn't explain all the houses and cars directly on the beach. Does he own all those houses too?
I'm not sure about the law in the US and California, but in some jurisdictions you can't just move an easement. There was an easement running through his property from the road to a specific point on the beach. He can't just move the ending point of the easement to a different spot on the beach.
