Justice (retired) Mian Hamid Farooq has upheld the verdict handed out to Jamshed by the PCB in August.
Following his involvement in spot-fixing, Pakistan batsman Nasir Jamshed has been handed a 10-year ban by the PCB.
Jamshed had scored three back-to-back ODI hundreds for Pakistan against India in 2012/13.
The Pakistan Cricket Board on Thursday charged former Test opener Nasir Jamshed with multiple breaches of its Anti-corruption Code of Conduct
Pakistan opener Nasir Jamshed has been handed a one-year ban by Pakistan Cricket Board (PCB) relating to the Pakistan Super League (PSL) spot-fixing case.
Sharjeel Khan and Khalid Latif have already been found guilty, and PCB has to give its verdict on Nasir Jamshed's involvement in the same case.
Nasir Jamshed, who represented Pakistan in two Tests, 48 ODIs and 18 T20Is, was earlier arrested by Britain's National Crime Agency in connection with the alleged spot-fixing case.
Nasir Jamshed also charged the PCB for pressurising the players to testify against him.
The board chairman Shaharyar Khan had said that Jamshed has been avoiding the PCB’s anti-corruption officials and lawyers by constantly changing his numbers and addresses in the United Kingdom (UK) where he is currently staying.
Nasir Jamshed is the fifth player charged in the scandal which saw a one-year ban, six months suspended, and a fine meted out to fast bowler Mohammad Irfan last month.
