The difficulty in changing the known laws of physics is that they still have to apply to everything else that has already been observed correctly. So it's probably true that there is another planet out there given these observations, but it's not impossible that the laws of physics themselves need further adjustments.

The article doesn't even state it this strongly. The claim is that planet 9 is the best explanation. Another explanation offered is that there was a previous planet that affected the existing planet's orbits and it is no longer there.

The article also notes that this claim is being made by the same scientist that popularized the idea of a planet 9.

There is plenty of room for doubting this specific planet 9 claim without changing any laws of physics.
