According to the outlet’s account, the warrants had been issued as part of a police investigation in the United Kingdom and were subsequently annulled by a London-based judge.
Al Jazeera reports that police admitted there had been a legal error relating to the warrants. The report does not specify the nature of the error.
The judicial decision, again according to Al Jazeera, did not close the investigation. The judge indicated that the legal error did not bring the investigation to an end.
The matter therefore involves two distinct aspects: on the one hand, the annulment of the warrants, and on the other, the continuation of the investigation involving Andrew. This is the distinction reported by the source.
The material provided identifies neither the police force nor the judge, and does not specify the subject of the investigation. Al Jazeera describes Andrew only as a former British prince.
The report therefore documents the annulment of the warrants and the acknowledgment of the legal error, while also stating that the investigation has not been declared concluded.
