"We are protesting against the shifting and future bifurcation of other courts," the Co-ordination Committee of All District Court Bar Associations of Delhi said.
The Committee quoted the Delhi government as saying that there were 400 lawyers chambers in the new building.
"But the building plan reveals there is no provision for lawyers' chambers," said spokesperson Sanjeev Nasiar. He said that the decision was taken unilaterally.
The strike will be observed in all six district courts -- Patiala House, Tis Hazari, Rohini, Karkardooma, Saket and Dwarka.
