The executive committee of OBA also resolved to suspend the membership of two advocates, who allegedly flouted its February 12 resolution regarding abstaining from work.
The resolution was passed in an emergency meeting of governing council of the association, OBA general secretary R D Shahi said.
The executive committee discussed the ongoing situation following lathicharge on advocates on February 10, he said.
Lawyers of the Allahabad High Court's Lucknow bench went on rampage on February 10, torching a state transport bus and vandalising some vehicles after the body of 40-year-old advocate Sharavan Kumar Verma bearing injury marks was found in the state capital the day before.
