1. While the Georgia Public Service Commission is vested with the power to regulate the business of engaging as a motor carrier of persons or property for hire over the public highways of the State (Code, § 68-603), and no person shall so engage without first obtaining from the commission a certificate of public convenience and necessity (§ 68-604), and while the commission in the issuance of the certificate may attach thereto such reasonable terms and conditions as in its judgment the public interest may require (§ 68-605), and in issuing such a certificate the commission must take into consideration the matters specified in Code § 68-609, and is authorized to adopt such rules and orders as it may deem necessary in the enforcement of the provisions of the Motor Common Carrier Act, approved August 27, 1931 (Code, § 68-629), and, therefore, acts in a quasi-legislative manner

v.
Georgia Public Service Commission,

Ga.

2. The transportation by the plaintiff of asphalt as a highway material under its Class “B” Certificate of Public Convenience and Necessity was not violative of Rule 8-a of the Public Service Commission, which provides that “Motor carriers operating under Class ‘B’ Certificates must not, without the written consent and approval of the Commission first being obtained, receive property at a point located on a fixed route and destined to a point located on a fixed route, or where through or joint service is being operated between such points; but m'ay receive property at a point not located on a fixed route and destined to a point on a fixed route; or may receive property at a point on a fixed route and destined to a point not on a fixed route,” since the certificate here involved contains the written consent and approval of the commission to transport “highway material between all points in Georgia but over no fixed route,” and the commission in its order and judgment in this case found that “it is common knowledge that asphalt is a material used in the construction of highways.”
3. Applying the foregoing rulings to the allegations of the petition, the trial court did not err in overruling the general demurrers of the Georgia Public Service Commission and its members, and of the two competing carriers, to the petition, which sought to declare invalid and to enjoin the enforcement of the order and judgment of the Georgia Public Service Commission, and in restraining the defendants from requiring the plaintiff to discontinue transportation of asphalt in tank trucks in *660 intrastate commerce between points in Georgia, and from enforcing the order and decision that would have that result.
Judgment affirmed.
