The Orange Democratic Movement rebels have vowed to challenge the party's move to expel them from the party.
The leaders have written to the party's Special Governing Council to be given a chance to explain themselves and have vowed to use all other avenues provided by the law to retain their seats in case their appeals fail.
Nominated MP Isaac Mwaura has said they will challenge the move in all the courts through their lawyer Kioko Kilukumi.
''We will appeal against the move in the Appeals court and further in the Supreme Court,'' said Mwaura who further doubted the party's disciplinary committee that is in charge of the entire process saying no procedures were followed in setting it up.
''We have a case to argue, we can even challenge the entire process because we are not aware who elected the disciplinary committee," he said.
The ODM has written to the Registrar of Political Parties to remove the rebels' names from the party members' list only days after writing to the House Speaker Justin Muturi to have them removed from parliamentary committees.
However, some of the MPs have remained unmoved saying they will still win in the event there are by-elections, with Mathare lawmaker Stephen Kariuki saying he will retain his seat on a Jubilee seat.
''I am not afraid of a by-election and even if we go back to the polls I will retain my seat on a Jubilee ticket,''he said.
The expelled leaders are Kwale county boss Salim Mvurya, Kisii Deputy Governor Joash Maangi, MPs Ababu Namwamba (Budalang'i), Samuel Arama (Nakuru West), Masoud Mwahima [Likoni], John Waluke of Sirisia, Stephen Kariuki of Mathare, Isaac Mwaura (Nominated), Kwale woman representative Zainab Chidzuga and Viwandani MCA Samwel Nyangwara.
The leaders have openly pledged their willingness to work with President Kenyatta's Jubilee Party in what have been seen as party defection.
