Ghadi said that the party would challenge the Mumbai police move in court on Monday.
Among other charges, the duo is accused of indulging in violent activities against north Indians living and working in Mumbai.
Last February, when the MNS versus north Indians agitation was first launched, the Mumbai police slapped externment orders on several MNS activists, including some women party members, but the courts cancelled all of them, Ghadi said.
