While the working methods of the International Court of Justice have been criticized in the past for their excessive slowness and formalism, the reforms introduced by the Court in the past two decades have led to considerable improvement. Recently, the ‘clients’ of the Court have expressed paradoxical desires for the Court to be more assertive in the management of the written and oral procedure and, at the same time, more responsive to the procedural views of the parties. Moreover, there are many requests for more interaction between the Bench and the parties and their counsel. If the good administration of justice rests on a careful blend between, on the one hand, formalism and solemnity, and, on the other, flexibility and dynamism, this cannot be achieved at the expense of the equality of the parties or of the procedural predictability. Hence, it may be desirable to amend the Rules in order to improve and modernize the procedure.
