Businessman Ben Gethi, his co-accused Josephine Kabura and eight others failed to appear in a criminal court on Friday.
They are wanted in court to plead to 15 counts of money laundering in relation to the Sh791 million lost from the National Youth Service.
The suspects were first expected in court on March 8, but did not turn up, claiming one of them had obtained orders halting their trial.
A judge has since clarified that the interim order applied only to lawyer Patrick Ogolla, who has since lodged a petition challenging his prosecution.
Senior Principal Magistrate Joyce Gadana on Friday issued fresh summonses against the suspects and ordered that they present themselves in court on April 14.
A team of lawyers representing the suspects in the pending case had protested that their clients had not been "properly served with the court summons”.
In her ruling. Ms Gandani said the suspects should be served afresh personally or through the media.
"I am not satisfied with the manner in which the suspects were served, and I hereby direct that the prosecution serves them afresh," she said.
The magistrate directed that if the suspects "cannot be served individually, the Director of Public Prosecutions should publish the summons in two local dailies with a national reach".
Two lawyers were served in court after they told the court that they would be representing two of the suspects.
Mr Ham Kiplagat, who represents Mr Antony Gethi, informed the court that his client was in hospital and could not make it to court. Mr Paul Amuga, for Mr Samuel Mudanyi, was also given the summons in court.
Other lawyers asked that the suspects be served "personally."
Prosecutor Eddy Kadebe told the court that the investigating officer was having trouble reaching the suspects to serve them with the summonses.
