Andrew Milroy, a 15-year-old British expat, had been living with his parents in Spain for several years when he was stabbed during an altercation outside a club in the holiday resort of Lloret del Mar last month.
Two men aged 21 wanted for his murder were arrested a week later at their homes in the north and south east of France.
Both men admitted being involved in the fight which took place as they were leaving the club, but said they didn't know the youth had died. Both returned to France the following day.
During the Lyon court hearing today, the prosecution called for the two suspects, one a mechanic, the other a builder, to be extradited to Spain.
The suspects may still have the chance to take their fight against extradition to France's highest court of appeal, even if arrest warrants are issued.
