Should Defendant file Second Civil Appeal or SLP before Supreme Court?

After the Civil Suit for declaration and permanent injunction was decided in favor of the Plaintiffs by the Ld. District Judge in Rajnandgaon, Chhattisgarh, and the Regular First Appeal filed by the Defendant was decided against them by the Two Judge Bench of the Hon'ble High Court, the suit was decided in favor of the Plaintiffs in both courts. What should the Defendant now file before the Hon'ble Supreme Court: (A) Second Civil Appeal or (B) Special Leave Petition (SLP)? Additionally, is it mandatory for the Defendant to obtain a certificate from the Hon'ble High Court before filing a Second Civil Appeal or SLP before the Hon'ble Supreme Court?
