Can you maybe substantiate this a little? I don't understand why a company recording the meetings of their employees, on company time and regarding company business, would be illegal.
(An individual doing so, on the other hand, might be problematic.)
This would definitely be illegal in Germany where I work as CTO.
Even having employees sign some letter of acceptance of such would still be illegal as a court would assume an employee was in an uneven power position and therefore not able to refuse even if they wanted to.
