Russia's appeal against the blanket ban imposed by Paralympics officials was rejected Tuesday - ending any hope the country's Paralympians had of competing in Rio.

The Court for the Arbitration of Sport upheld the decision made by the International Paralympic Committee following allegations of state-sponsored doping.

A statement for CAS found that the IPC "did not violate any procedural rule in dealing with the with the disciplinary process" which led to the suspension of the Russian Paralympic committee.

It added that the decision to ban Russia, "was made in accordance with the IPC rules and was proportionate in the circumstances."

Russian sports minister Vitaly Mutko told the Tass news agency that the decision was "more political than judicial."

Russia has "catastrophically failed its para athletes. Their medals-over-morals mentality disgusts me," he said at the time.

The IPC had sought more information from Richard McLaren, who led the independent report for the World Anti-Doping Agency which alleged wide scale doping which had allegedly been covered up by the country's security services.

Reacting to the verdict Tuesday, Craven said his organization was "greatly encouraged."

"Today's decision underlines our strong belief that doping has absolutely no place in Paralympic sport, and further improves our ability to ensure fair competition and a level playing field for all Para athletes around the world," he said in a statement.

"Although we are pleased with the decision, it is not a day for celebration and we have enormous sympathy for the Russian athletes who will now miss out on the Rio 2016 Paralympic Games.

"It is a sad day for the Paralympic Movement, but we hope also a new beginning. We hope this decision acts as a catalyst for change in Russia and we can welcome the Russian Paralympic Committee back as a member safe in the knowledge that it is fulfilling its obligations to ensure fair competition for all.

"Beyond Rio 2016, we will work with the World Anti-Doping Agency to establish the criteria the Russian Paralympic Committee needs to meet in order to fulfil all its membership obligations and have its suspension lifted."

The IPC's decision to impose a blanket ban on Russian Paralympians was in complete contrast to the International Olympic Committee.

The IOC asked each individual sporting federation to decide whether athletes could compete.

A three-person IOC panel then had the final say - allowing 271 Russians to take part in Rio with the team winning 56 medals.
