Rio 2016 Paralympics: Russia contest Court of Arbitration for Sport decision
Russia have contested the Court of Arbitration for Sport's (Cas) decision to uphold the country's blanket ban from the Paralympics.
Cas then rejected a Russian Paralympic Committee (RPC) appeal against the ban earlier this week.
At least 266 Russian competitors are expected to now lodge individual cases.
The RPC's appeal, launched in the Swiss Federal Court, will be held on Monday.
Only Russian track and field athletes were banned from the Olympic Games, with individual sports' governing bodies deciding if they could compete, but the Paralympics ban includes all of the country's competitors.
Russian President Vladimir Putin said on Thursday the IPC's ban was "outside the bounds of law, morality and humanity".
