I'm not sure how you read legalization into that statement. It sounds more like the local police have asked an investigation unit to determine whether or not to go ahead with an investigation or prosecution. I'm not familiar with drug classification for legal purposes in your country, but in mine there have been more than a couple misguided people who have misread law and claim to dispense legal ayahuasca. None have been prosecuted, other than the. Sante Daime and UDV cases, but some have been shut down by the very ayahuasca community to try to head of potential damage to 'the cause'.
The thing is here, until somebody gets hurt, it's but really a law enforcement priority.
I don't see things like this as positive. People who have done it a couple times and suddenly get a shaman complex, thinking they can guide ceremony because they have been guided. Imo, that's like saying you can fly an airliner after one goes on a flight or two.
