Other proposals which may be implemented without primary legislation are also under active consideration, including the Court of Session Rules Council''s consideration of recommendations on both multi-party actions and protective cost orders in public interest litigation, and the government''s consideration of the requirements for a review of the cost and funding of litigation. The large group of recommendations for structural changes to the judicial hierarchy and for the different handling of cases in the proposed new structures are closely intertwined and currently subject to a costing exercise being undertaken jointly by the Scottish Court Service and the Scottish Government; the costs of recommended reform will be jointly considered by the government and the judicial working group established by the Lord President before the government publish a formal response to the recommendations, later in 2010.
