UTC, there is a significant difference between whether or not someone has the "right" to do something and whether or not it is legal, which is not the question you asked.
I would assert that we all have the right to record a JW judicial meeting even if it is illegal in your particular jurisdiction. In many locales, recordings must be explicitly approved and agreed to by all parties, so you better check before you plan to record a judicial committee meeting. Since JW elders will never agree to it, any recording would have to be done surreptitiously and without the permission of the elders. Therefore, if one were to secretly record a judicial meeting, they would be breaking the law in many jurisdictions. That, however, does NOT mean it is wrong.
But whenever an individual commits a deliberate, intentional act of civil disobedience and breaks a law because they think it is wrong, they also better be prepared to accept the possible consequences. This could possibly mean fines and or jail time. But frankly I think that's a pretty remote possibility given the circumstances. (But this is must my opinion and is explicitly NOT meant to be legal advice!)
Here, for your reading pleasure and edification, is an older thread that explores both HOW to record a judicial meeting as well as various reasons WHY and/or why you may not want to do that.
