The lawsuit isn't for continued access to work; the entity that initially hired him and agreed to the terms had an opportunity to negotiate continued/expanded access either before the contract was executed or in the intervening three years. The lawsuit is because the entity elected to ignore the previously negotiated contract. Intentional or accidental is for a court to decide.
If the award for breach of contract was simply the fee that would have been due, then there would be no incentive to bother honoring contracts -- you could simply pretend it didn't exist, not pay until someone noticed, and then get off with the same cost as you would have paid had both parties been diligent. No, lawsuits relating to breaches of contract are for additional damages (and courts subsequently award said damages) to punish the offending party as a deterrent to those who would shirk the responsibilities of a contract in the first place.
