Speaking in a Kitale Court during the hearing of a petition filed against Trans Nzoia Governor Patrick Khaemba, Mr Wamalwa recalled that President Kenyatta openly promised to fix the judiciary after the August election was annulled.
He claimed that the Supreme Court struck out most of the evidence presented by the petitioners who challenged the repeat poll.
The MP further stated that when Chief Justice David Maraga was reading the ruling on Monday, the judges' body language showed that they were under intimidation.
Wamalwa, however, asked the President and National Super Alliance (NASA) leader Raila Odinga to engage in dialogue so as to unite the country.
"President Uhuru openly promised to fix the judiciary after the annulment of his August win, the Monday's ruling clearly indicates that the intimidations worked," Wamalwa noted.
This comes after the Supreme Court dismissed petitions filed by Kilome MP Harun Mwau and activists Njonjo Mue and Khelef Khalifa on grounds that they lacked merit.
Maraga noted that the two presidential election petitions were consolidated and heard together because of time pressure and that the judges had arrived at the final decision unanimously.
In September, President Kenyatta publicly stated that he would revisit the issue of the Supreme Court if re-elected following the annulment of his victory.
