NCP national secretary Sachchidanand Singh served a legal notice on July 9, challenging Sunetra Pawar's election as party president.
The notice is addressed to Sunetra Pawar, national working president Praful Patel, and general secretary Brijmohan Shrivastav.
The NCP is managing a constitutional challenge to the presidency with no senior Pawar family patriarch in place for the first time in the party's 26-year history.
