"In accordance with Article 87(3) of the Rome Statute, the competent authorities of Kenya are requested to keep the request for assistance and any supporting documentation confidential except to the extent that disclosure is necessary for the execution of the request," he added.
Smedt further appealed to the Government to treat the matter with the utmost urgency so as to facilitate investigation by the prosecutorâs office.
Last week, Ruto beat a hasty about-turn following a pledge he had made to return the 100-acre piece of land he allegedly acquired illegally from Muteshi.
The change of heart occurred after the minster and the IDP failed to agree on certain conditions.
The case is now set to go to a full hearing paving way for tabling of details on how Ruto acquired the land in Kaptebei Settlement Scheme.
On Monday last week, Muteshi who was allegedly forcibly evicted from the piece of land, told a court that Ruto, who had agreed to surrender the land and relinquish the title deed for the property he bought from a woman, said he was not ready to accept that he acquired it illegally.
Muteshi had indicated through his lawyer Anthony Lubulela that he would only accept the property back if Ruto also catered for the expenses he incurred filing the case.
Due to failure to record an agreement before High Court Judge Lady Justice Rose Ougo as ordered two weeks ago, the judge ordered the matter to be heard on April 25 and 26.
