Can a landlord recover for rental arrears that are over one year old in a non-payment proceeding?

Yes.

yes.

I thought that the doctrine of latches can be applied here. What do you think?

In what way are the landlord's hands "unclean" that would make you think the doctrine of laches applies?

This is merely an unpaid debt, subject to SOL, if they wait over that period to sue.

Did you rely upon the fact that they didn't immediately hound you for the rent? Most forms of estoppel require some sort of detrimental reliance on the part of the person who is claiming estoppel.
