Legal Question in Landlord & Tenant Law in California

Yes they can. No it was not void. Nothing to do with UD or 3-day notices would void a lease. They are tools to ENFORCE a lease and obtain remedies for the tenant's breach of the lease.

If a California court dismisses the unlawful detainer matter without prejudice, the Plaintiff (landlord) may refile another matter. It would not make sense to refile with the old 3 day notice to pay or quit, since it could be considered waived by the Court. Plaintiff could certainly submit a new 3 day notice that is merited by the circumstances at the time (non-payment of rent, for example) and then re-file an unlawful detainer matter based on the new 3 day notice.
