On 23 July 2002, Israel executed a targeted killing operation against the head of the Hamas military wing in Gaza, Salah Shehadeh. This operation resulted in the death of Shehadeh and 14 other people, and the injury of 150 persons. Pursuant to that attack and the Israeli High Court's recommendation, Israel established a special committee to examine the killing of Shehadeh and the collateral damage that it caused, the justification for the operation, and the possibility of recourse to alternative measures at the time.
On 29 January 2009, the Central Magistrates Court Number Four of the High Court in Madrid issued a decision in the preliminary proceedings regarding a criminal case against several high-ranking Israeli officials.[2] Judge Fernando Andreu determined that the events may and must be investigated by the Spanish courts, and ordered the initiation of an official inquiry.
On 6 May 2009, Spanish prosecutors appealed Judge Andreu's decision,[3] and requested the termination of the investigation, emphasizing the fact that Israel has the closest jurisdictional link to the events in question and, therefore, has preference and priority over the jurisdiction of Spain, which lacks any reasonable connection to the events or to the affected parties. Moreover, the prosecutors stated that an investigation had already been initiated in Israel as a result of a judicial order issued by the Israeli Supreme Court, and since the investigating body is authorized to publish operative conclusions and determine whether there are grounds to establish whether a crime has been committed, it is clearly a judicial investigation.
On 20 June 2009, the National Court of Appeals accepted the prosecutors’ request and voted 14-4 in favor of the dismissal of the inquiry due to the Spanish courts’ lack of jurisdiction over the matter and since an Israeli investigation is still pending, which the Court considers genuine and legitimate.[4]
On 5 April 2010, the Spanish Supreme Court published its decision to reject an appeal against the National Court of Appeals’ decision.
