He faulted former President Uhuru Kenyatta's regime for contempt of court orders.
"Let it be known that all those court orders that were accumulated will be enforced. Without justice you cannot have peace and reconciliation," he said.
"Those who behaved with impunity and held the State at ransom will be held to account."
Months after officiating the swearing in of ODM leader Raila Odinga as the "People's President" on the basis of having a dual citizenship of Canada and Kenya, Miguna was deported in a dramatic scene at the Jomo Kenyatta International Airport, Nairobi where he was forcefully ejected.
After his arrest, he was locked up incommunicado for five days, being shuttled between police stations in Kiambu and Kajiado before his deportation despite a court injunction against the same.
But the decision of the government did not last long after the High Court quashed the government decision to strip him his citizenship and deporting him
An application was then filed on Miguna's behalf before Judge Enock Chacha Mwita, who said he was amazed by the nature of the case as he has never witnessed such an incident "where a person said to be a citizen has been deported to another country and declared a prohibited immigrant, thus unwelcome in a country he calls his birth place."
And as his travel woos deepened, he then wrote another application to the court to help him get back his Kenyan passport and brought back to Kenya at the government's expense.
In replying affidavits, Matiang'i said Miguna had never denounced his Canadian citizenship yet he got it at a time when it was illegal to hold a dual citizenship in the country.
Judge Mwita also ordered the director of immigration to issue Miguna with travel documents allowing him to return to Kenya and that the government was to "facilitate" his re-entry and he should remain in the country until the conclusion of the case.
He ordered Matiang'i and Immigration PS Gordon Kihalangwa to jointly pay lawyer Miguna Sh7.2 million from their pockets.
Miguna was cleared back in the country, after President William Ruto issued him a new passport and lifted the red alert imposed on him that was making it impossible for him to jet in the country.
