Not quite so, rojash.
I don’t believe the Express (nor indeed the Telegraph nor even the BBC, who also ran the story) is confusing the issue at all. It is perfectly straightforward. AOG hasn’t got it quite correct, but the effect is the same. The 1951 Convention on Refugees requires refugees to seek asylum in the first “designated safe” country they enter. In making this ruling the ECJ has declared Greece a “non-safe” country. Were it safe the UK would be perfectly entitled to refuse to hear the asylum claims of people who had arrived here via Greece. They could have been returned to Greece forthwith. Now their claims must be heard here, and if unsuccessful they must be returned to their own country (a task that often proves impossible because most of them arrive “sans papiers”).
The ECJ (or more properly the EU) should be making urgent enquiries as to why Greece’s asylum arrangements do not comply with European standards. Still, with Croatia just joined up to the club, I imagine their efforts will be more urgently needed elsewhere.
