German Gracia Schuette and Syrian Aeham Ahmad both had their lives changed forever by Angela Merkel's decision in 2015 to leave Germany's doors open to hundreds of thousands of refugees.
The deportation of refugees under EU law from northern European countries to their southern counterparts has come under criticism in recent years. The court ruled however that such deportations were justified under the 'mutual trust' principle.
Germany is once again sending Syrian refugees back to the EU country where they first arrived, in line with the so-called Dublin regulations, the government confirmed on Tuesday.
UPDATE: As over 1,000 refugees arrived in Munich from Hungary by train on Tuesday, police in the Bavarian capital said they were "overwhelmed" by the amount of food, water and other supplies donated by local people to those in need.
After Hungary announced that it would stop obeying EU rules on refugees, the country's ambassador came in for a stern talking-to from both the Foreign and Interior ministries in Berlin.
