Indian Law Corpus for Continued Pretraining

Plain text of Indian law for continued pretraining: the Constitution of India (as on 1 May 2026), central Acts of Parliament, state Acts, central and state Rules and Regulations, the repealed criminal codes still applied by courts (IPC, CrPC, Indian Evidence Act), the official BPRD correspondence tables between the old and new criminal laws, and the English judgments of the Supreme Court of India (1950-2024), which bind every court under Article 141. Statutes come from official sources (India Code, the Legislative Department, the Gazette of India, PRS India, ministries), every PDF pinned by SHA-256 in the build repository; judgments come from the Supreme Court's own website via the sinhal/Indian_Supreme_Court_Judgments dataset (openrail licence).

general is replay text: a seeded random sample of FineWeb-Edu (about 10% of the mix) so the model keeps its general English and reasoning while it learns the law.

All documents are in one train split. A recipe holds back its own small random validation slice.

Every document appears 2 times: the original and its copies, whose id ends in -copy2, -copy3 and so on. One pass over this dataset trains on each document 2 times. A random validation slice will often hold a document whose copy is in training, so its loss reads lower than on truly unseen text.

Cleaning

Footnotes (detected by their smaller print), page headers, contents pages, Gazette boilerplate, Hindi and legacy-font text and the overlaid "BILL" stamp are removed; section titles printed in the margin are put back next to their section number; amendment Acts and Bills are left out because their changes are already in the consolidated texts. Checked against an independent answer key: the Bharatiya Nyaya Sanhita (358/358 sections), Bharatiya Nagarik Suraksha Sanhita (531/531) and Bharatiya Sakshya Adhiniyam (170/170) match in number and title.

Licence

Texts of Acts, the Constitution and government publications are not infringed by reproduction under section 52(1)(q) of the Copyright Act, 1957. Supreme Court judgments are from the sinhal/Indian_Supreme_Court_Judgments dataset (OpenRAIL). The general rows are from HuggingFaceFW/fineweb-edu, licensed ODC-By 1.0.

Judgments name the parties as published by the Supreme Court; some older judgments may identify people whose identity the law now protects. Keep this dataset private and do not republish it.
