Dear Mr. Sugam Puri
for your question, answer is in Limitation Act 1963, Division II, Appeal Section,
see Article 115
point (a) is for death sentence and
point (b) is for any other sentence, now therefore the conviction appeals are to be filed within sixty days to HC.
and second part of piont (b) talks about any order not being an order of acquittal.
i think this will satisfy your query.
