At least eight MPs from the larger Gusii region may be recalled following the passage of the controversial Finance Bill.
On Thursday, in a chaotic parliament, President Uhuru Kenyatta's proposal on new taxation was passed despite resistance from majority of MPs.
Nyamira Youth Bunge, a lobby group associated with fighting for good governance, has accused the MPs of cheating Kenyans in the debate.
"We shall recall them soon. The process is underway because the constitution gives us such powers.
"It is shameful that they hid when we needed then the most. We did not see some coming out in public and that gives us a reason to conclude they supported the bill," said Beavon Magare.
Those in real danger are Jimmy Angwenyi, Ezekiel Machogu, Richard Tong'i, and Innocent Obiria.
Others are Prof. Zedoc Ogutu, Ben Momanyi, Joash Nyamoko and Shadrack Mose.
The second group, even though it appeared to oppose, it's accused of playing cards to please both the public and the people.
