"You (government and other authorities) had to comply with our order and directions, but you have not done so," a bench of justices B D Ahmed and Sanjeev Sachdeva said.
"It is money going down the drain, let me tell you this," Justice Sachdeva also remarked with respect to work the Public Works Department (PWD) claimed to have done to decongest traffic.
It said that subsequent to it apprising the court about these measures, PWD was allowed to go on with its project of building a three-lane flyover from Munirka till Army Research and Referral Hospital on the Outer Ring Road, parallel to the existing Rao Tula Ram flyover.
The residents of Vasant Vihar, who have filed an application alleging "abject failure" on the part of PWD to comply with court directions, contended that encroachments are still present on the Nelson Mandela Marg junction as well as DDA bypass road.
The bench, however, remarked that no useful discussion could be had without having a map of the area and listed the matter for further hearing on September 9.
It also issued notice to the city government and other authorities and asked them to file status reports in response to the contentions made in a fresh application moved by residents of Vasant Vihar.
