affidavit it is mentioned that Section 4(1) notification was issued, no details have been furnished and the petitioners in the reply affidavit, have refuted the said contention also. What is evident from the counter affidavit is only that an alignment was approved by the Government and boundary stones have been planted. But as noted already, the second respondent has sought to justify the action relying upon the provisions of the Highway Protection Act, which obviously, in the absence of a notification under Section 18(2) of the Act, cannot help the second respondent in issuing a stop memo. In fact, the Government by Ext.P9 circular, was also of the view that the restrictions under the Highway Protection Act can be enforced only after publication of a notification under Section 18 and so far no such notification has been issued and therefore the building permits can be issued. Even though it is sought to be explained away in the additional counter affidavit, by stating that the same applies only in the case of the area between building line and control line, as already noticed, since the notification under Section 18(2) is not issued, such a contention cannot be accepted.
