Pets in rental properties. Has Tenancy Tribunal got this right?

We have seen a trend in the Tenancy Tribunal in the past few weeks. A number of adjudicators are throwing out pet clauses saying they are unenforceable. Does this mean that tenants are now allowed pets and landlords can do nothing about it? We also get an opinion from ChatGPT on the matter. It is unbelievable to listen to. From obese Guinea Pigs to Flemish rabbits. This show has it all.
