Pfizer denies all the charges. It argues it was meningitis, not Trovan, which killed the children or damaged their health. It says Trovan saved lives and was as effective as the other, established drug used for comparison in the trial.
The federal and state governments had embarked on an out-of-court negotiation process with Pfizer and several meetings took place over the past few weeks. The next one is supposed to take place in London on Dec. 12.
But the Kano attorney general and commissioner for justice, Aliyu Umar, said the state would not be taking part because it was dissatisfied with how the talks were going.
"They are just trying to play with our intelligence. They have not shown any seriousness. The Kano team will not go to London to sit with them again," Umar told Reuters in his office shortly after the latest court hearing in the civil case.
A federal Ministry of Justice spokesman said President Umaru Yar'Adua had instructed that the case was to be pursued in court and Attorney-General Michael Aondoakaa would comply with that.
"There had been moves to terminate the case but I blocked them," the ministry spokesman quoted Aondoakaa as saying.
The civil and criminal cases are being heard separately in courts in Kano, Abuja and Lagos. They have developed into a tangle of unresolved petitions and side issues, dragging on from one adjournment to the next since May. No witness has been heard and no substantive issue tackled.
In Wednesday's hearing in Kano on the state government's civil suit, the court adjourned the matter until Jan. 28, when it said it would rule on whether it had jurisdiction.
Outside the courtroom, a few dozen people who said they were parents of the alleged victims of Trovan protested against the drugmaker. Some held placards with the names of their children.
"Pfizer killed my son, Mustapha Tukur, and I want Pfizer punished," read one of the placards.
Pfizer had issued a statement on the out-of-court talks from its New York office on Nov. 27 which read: "Pfizer welcomes dialogue conducive to an appropriate resolution of its differences with the federal and Kano state governments and remains committed to any such discussions."
"Unsubstantiated allegations coupled with exorbitant monetary demands, however, will impede that process."
