Your question is not particularly clear, but it sounds like you're describing a situation where:
- The tenant doesn't pay the rent
- The landlord files an action to evict the tenant, and
- The tenant files a request for a jury trial.
The act of filing for a jury trial doesn't guarantee that the tenant won't be evicted, but it will likely make the eviction process more time-consuming and expensive for the landlord.
I'm assuming the tenant is entitled to a jury trial--otherwise this would be useless as a stalling tactic. In that case, the question you really want answered is, can the landlord force the tenant to waive any right to a jury trial by contract, for example in the lease?
In California, the answer is no. The linked document suggests that you may be able to specify some form of ADR, which would avoid the expense of a jury trial, but the California courts won't let you get away with a straight jury trial waiver.
