22. Justice Madan B. Lokur, the first author of the judgment dealt with the issue as to whether the conviction could be sustained by this Court or it was only the sentence which was to be dealt with in accordance with the 2000 Act. Almost all the previous judgments were referred to in paragraphs 24, 24.1 to 24.7, 25, 25.1 to 25.2, 26, 26.1 to 26.2 and 27 of the report with respect to all the four categories of the cases wherein different views have been taken by this Court. The first category was where conviction was upheld but sentence quashed. The second category was where conviction was upheld but sentence was modified to the period already undergone. The third category was where conviction and sentence both were set aside and the fourth category was where the conviction was upheld and the matter referred to the JJB for awarding a suitable sentence. In paragraph 28 of the report Justice Lokur sums up the four categories. Further in paragraph 29, reference is made to section 20 of the 2000 Act and it was finally concluded in paragraph 22
