Uhuru Kenyatta won a repeat election in October, boycotted by Mr Odinga.
"IN EXERCISE of the powers conferred by section 22 of the organized Crimes Act of 2010, the Cabinet Secretary, Ministry of Interior and National Government declares National Resistance movement (NRM) to be organized criminal group for the purposes of the Act".
Mr Musyoka was to take the oath as Mr Odinga's deputy as the opposition leader declared himself "the people's president".
Kenyatta was inaugurated in November, and Kenya Attorney-General Githu Muigai warned that an opposition group swearing in a president who's not officially been declared the victor is high treason - an offense that can result in death.
On Monday, Linus Kaikai, chairman of the Kenya Editors Guild, said senior editors had been summoned by the authorities and warned not to cover the event or risk being shut down.More news: Jamie Lee Curtis starts shooting for 'Halloween'

The Anglican Church leader is quoted by Citizen TV to have urged that the "swearing in" may not automatically give NASA an opportunity to forcefully take over government, hence, "there should be no need for panic". However, Odinga made a decision to boycott the election because he still wasn't happy that enough significant reforms had been introduced to make the election free and fair.
RMS managing director Wachira Waruru said: "We would like to confirm that, this morning, the Communication Authority disconnected Citizen and Inooro TV transmission".
"Kenya is on a very slippery trajectory in regard to human rights, and president Kenyatta urgently needs to reverse this trend", Namwaya said. Both had planned live coverage of Odinga's swearing-in event. "For Kenyatta, continued pressure from Odinga and NASA supporters will push his administration to pursue policies that ensure its credibility and popularity", such as increased social spending and free secondary school education, Atwell explained. Although heavy police deployment was withdrawn on Tuesday, police used tear gas to disperse supporters.
Three main private television channels in the country had their live feeds cut or blocked, while the state-run Kenya Broadcasting Corporation (KBC) was allowed to continue.
Last week the opposition released what it called "authentic" election results showing Odinga won the August vote, but it refused to say how it obtained the information from the electoral commission's computer servers.
