Commercial landlords have all the rights they need in that regard. It’s a contract dispute and a court will order remedies like any other contract dispute. You don’t want to give landlords unilateral powers to interpret and enforce contracts. That would be pretty dumb.
Most landlords don’t do this because they find that negotiating with a company to privately and quietly reduce rent and/or leasing space over a negotiated period of time is a much better alternative for all parties.
Musk could have also got the same, but he decided to go fill scorched earth so it will have to go through the legal system instead.
"Landlord rights" is a red herring here. Companies got away with this because their financial positions changed drastically, and since it happened across the market, so did their bargaining positions. The corporate real estate market seemingly hasn't recovered and is still running on fumes, so it's not surprising similar hardball negotiations continue. It's a bad look and I'm no fan of the chief Twitter addict, but I'd file this article in the meaningless noise about celebrities bin.
Corporations are not people. Corporations can enter into contracts that humans would be protected from. This is a straight-up contract dispute between corporations. Twitter could get locked out of some of their offices and possibly even data centers, and the contents of those buildings could get sold off to pay down back rent.
They can repossess the building but it’s not like they will be able to re rent it. The office space glut may allow them to re negotiate the contract trump style
Commercial landlording is different than residential, but in residential, just changing the locks sets you up for a lot of trouble.
Power would only really be an issue if anything important was running in their offices, but running servers in the office has been unfashionable for quite some time, so I wouldn't expect much if anything to break there.
I will bet my keyboard that every big tech company ends up having some mission critical thing running on a machine in their office. They don't know they have that thing, but it's there and will become apparent when the power is shut off.
You don't have to have an expensive or lengthy suit to evict a commercial tenant... you just can't do it unilaterally. You can go straight to the court and request an eviction, you do not need to sue Twitter to evict them.
How many "eviction lawsuits" have you been involved in?
