15. The most revealing evidence of an evolution in the jurisprudence of the Committee is the increasing number of individual opinions appended by members of the Committee to decisions on admissibility (rule 92 (3)) or final views (rule 94 (3)) of the rules of procedure, whether concurring or dissenting. This trend emulates the procedures of other international and regional human rights bodies and is a welcome development for the progressive development of human rights law and public international law in general. Whereas only three individual opinions were reflected in Volume 2 covering 16 sessions, 16 individual opinions were recorded during the 7 sessions covered by this Volume, including 13 opinions (seven in the "views" and-six in the admissibility stage) relative to the thirty-seventh to thirtyninth sessions. __________ 3 International Covenant on Civil and Political Rights, Selected Decisions under the Optional Protocol (33rd - 39th sessions), New York, 1990. French and Spanish versions were published in 1991. 16. The aforementioned trend is an illustration of a number of formal and substantial changes in the approach of the Human Rights Committee to its jurisprudence: (a) a growing erosion of consensus as a decision-making process; (b) it reflects the increasing complexity of com-munications both in respect of the factual and the legal situation; (c) attempts to speed up the decision-making pro-cess through improving the quality and the quasi-judicial nature of the procedure. 17. The working group on communications was given with effect from the thirty-fifth session the power to declare cases admissible provided that all members of the working group and all other members so agree (unanimity requirement).
