The ruling was in response to legal challenges from individual asylum seekers and the charity Asylum Aid.
The government has said it will appeal the ruling in the Supreme Court.
The Rwandan government has disputed the Court of Appeal's decision, saying that it has been recognised for its treatment of refugees.
The policy has faced criticism over Rwanda's human rights record and the government's plan to spend £169,000 on every asylum seeker forcibly removed to a third country.
An economic assessment for the Illegal Migration Bill shows that two in five small boats crossing the Channel would have to be deterred for the government to break even.
The Court of Appeal in the UK has ruled that the government's plan to deport asylum seekers to Rwanda may be risky and that there is a possibility of refoulement to other countries where they may face ill treatment.
This ruling comes from a challenge by ten asylum seekers from Syria, Iraq, Iran, Vietnam, Sudan, and Albania who arrived in the UK on small boats.
The court found that the High Court "showed excessive deference" to the Home Office's assessment that assurances made by the Rwandan authorities provide a sufficient guarantee to protect relocated asylum seekers from a risk of torture or inhuman treatment.
The Home Secretary, Suella Braverman, has expressed her commitment to the plan and insisted that Rwanda is a safe country, but the plans have been thwarted by protracted legal proceedings.
The Illegal Migration Bill was introduced into Parliament to stop anyone coming to the UK illegally after passing through a safe country from being allowed to stay in the country, and those migrants would be automatically detained and sent to their home country or a country such as Rwanda.
The Bill has suffered a series of defeats in the House of Lords on Tuesday night, as peers inserted demands that the new system complies with international treaties, prevents the detention of potential victims of human trafficking, and allows unaccompanied children to make asylum claims.
Rwanda has built a safe, secure, and dignified environment for migrants and refugees, and is committed to making the partnership with the government work.
The government is facing criticism for the Rwanda policy, which is seen as unworkable, unethical, and extortionate.
The court has found that the scheme was not legal or safe, and the government has been forced to admit that it will cost £169,000 to send each person to Rwanda, adding to the £140m already spent by taxpayers.
The government should focus on Labour's plan to tackle criminal gangs, clear the asylum backlog, and stop dangerous boat crossings, according to Yvette Cooper.
Sadiq Khan has described the policy as callous and unworkable, and it is seen as shaming the nation.
