The protesters alleged that the senior leadership in the state has "hatched a conspiracy to benefit other parties".
"There is a conspiracy behind the denial of ticket to the people who have worked throughout their life for the party," Mukesh, a supporter of Sethi, said.
Sethi was hopeful to contest the assembly elections on a party from the Jammu East constituency.
"Not only the front-runners have been ignored but also the mandate has given to the third and fourth rung leaders. I have been working for the party for the past 23 years, but they have denied me the ticket," Sethi claimed.
The Central Election Committee of BJP, which met in New Delhi on Sunday, announced the name of 45 candidates for the Jammu and Kashmir polls. In its first list of 45 candidates, the party has dropped names of seven of its 11 sitting MLA.
