Refusing to process asylum claims: the safe country and inadmissibility rules

Successive governments have wanted to introduce extra safeguards against non-genuine asylum claims and deter asylum seekers (whether or not genuine refugees) from making dangerous journeys to the UK. These include measures denying or limiting access to the asylum system to people from, or who have passed through, countries that the UK considers safe.

Europeans and Indians cannot normally claim asylum in the UK (‘inadmissibility’)

The UN Refugee Agency says that designating countries as safe as part of an asylum decision process is permitted under international law, but only as a way of prioritising which claims to examine. It is opposed to safe country rules that impose blanket bans on asylum claims by people of certain nationalities.

The closest thing to an automatic blanket ban on asylum claims is for citizens of European Union countries, plus a few others including India. Claims for refugee status by people from these countries must be declared “inadmissible” unless there are exceptional circumstances. An inadmissible claim cannot be considered: it is, essentially, null and void.

Some non-EU citizens have no right of appeal if refused asylum (‘certification’)

Certain non-EU countries are presumed to be safe for asylum seekers to return to unless they can show otherwise. People from so-called ‘white list’ countries do have their asylum claim considered but have no right of appeal if the claim is deemed to be clearly unfounded. Such a claim is said to be ‘certified’.

From 2015 to 2024 inclusive, 18,300 asylum claims were certified as clearly unfounded (12% of all asylum refusals in that period). This includes some people from countries not on the white list, which is possible under the certification legislation, although it has rarely happened in recent years.

Travel through a safe country can void a UK asylum claim (‘third country inadmissibility’)

The UK government’s position is that refugees should claim asylum in the first safe country they reach. The UN Refugee Agency says this is not required by the Refugee Convention or international law.

People who have passed through a safe country can nevertheless be denied access to the UK asylum system. The law allows the Home Secretary to declare an asylum claim inadmissible if the person “has a connection to a safe third State”. An inadmissible claim cannot be processed unless there are exceptional circumstances or removal from the UK would take too long.

When the UK was in the European Union, some people in this position could be sent back to an EU country that they had passed through. Those ‘Dublin’ arrangements lapsed after Brexit. From January 2021 to 30 June 2025, a total of 38 people were removed from the UK after having their asylum case deemed inadmissible.

The UK has tried to set up replacement removals agreements with Rwanda (under the Conservative government in 2022) and France (under the Labour government in 2025).

Removals to Rwanda and now France rely on complex third country inadmissibility rules

If someone being considered for removal to a country they are not from raises a legal objection based on the European Convention on Human Rights, that claim must be processed. Unlike their asylum claim, it is not being declared null and void.

This means that, if someone both claims asylum and raises a human rights claim, civil servants must make a complex series of assessments and decisions before the person can be removed as inadmissible. These decisions can be challenged by judicial review.

In December 2022, the High Court quashed a number of individual decisions relating to people being removed to Rwanda. The Supreme Court ultimately found the Rwanda deal as a whole unlawful because of the risk that the Rwandan authorities would send people back to unsafe countries of origin.

The treaty with France, signed in July 2025 as a one-year pilot programme, has so far proven less susceptible to legal challenge on either an individual or general basis. By time of writing, 94 people had been removed from the UK to France, while 57 had been admitted from France to the UK under its ‘one in, one out’ mechanism.
