The enforcement wing of the Chandigarh Union Territory razed around 50 illegal structures in Khuda Ali Sher village in Chandigarh, falling outside the lal dora. The term lal dora refers to village land that is used for nonagricultural purpose and villagers often use this area to keep their livestock. The landrevenue department marks these areas by tying a red thread (lal dor) as its boundary. Any construction outside it is considered illegal.The drive was carried out after directions from the Punjab and Haryana High Court, which had originally ordered the demolishing of the "illegal" buildings in 2003. On April 27, 2018, the enforcement staff demolished around 50 "illegal" structures, both residential and commercial, that were allegedly constructed after May 2012. According to reports  the buildings had been constructed on the catchment area of lake Sukhna and the High Court had banned the construction of buildings in the area. Officials from the Estate Office, along with the police demolished the buildings with excavators and bulldozers. The residents staged a protest and raised slogans against the administration and the Central Government. They also alleged the administration had carried out the drive without serving any prior notice, giving them no time to move their household items. They added that the Government has not provided them with any rehabilitation.
