C.R.S. § 40-10.1-701

(1) The general assembly finds and declares that: (a) Nothing in this part 7 requires or prohibits a motor carrier applying for a permit pursuant to section 40-10.1-702 (1)(a) to form a labor union nor requires any large-market taxicab service driver to join a labor union; and (b) If a motor carrier previously obtained a certificate of public convenience and necessity to provide taxicab service pursuant to section 40-10.1-201 and the certificate remains valid at a time that the motor carrier subsequently obtains a permit to operate large-market taxicab service under this part 7, the motor carrier’s certificate constitutes a devalued asset for the motor carrier.
