Could we make a list of the most relevant and credible Indian (or even international where Indian students can get published) journals to get published in

1) International arbitration
2) Human rights law
3) Company law
4) Technology law
5) Sports law
6) Media and entertainment law
7) TMT, construction law, real estate law
8) Construction law
9) Fintech law
10) Securities law
11) Banking, Bankruptcy and insolvency law
12) Competetion law
13) Capital markets

I am specifically interested in knowing #1 and #2 but I added other fields so that this conversation helps others too.

Most of the Indian journals including reputed ones are general themed and not specialized. Although there are some that specialize on one or other legal domain. For example, for technology, there is always IJLT of NLSIU or JIPR (if it involves an IP component) of NISCAIR. Latter is SCOPUS indexed too, though that is not necessarily an indicator of quality in itself. But JIPR has a good reputation even otherwise.

Highest ranked by whom? SCOPUS indexation isn't in itself a measurement of quality. Since SCOPUS does not list student-run journals at all, regardless of quality. I am not disputing that JGLS Law Review is of good quality, but reputation-wise it is nowhere near the top even within the country at present.

The Journal of the Indian Law Institute is quite renowned. Not sure if it still retains its brilliance, but it was the go to journal for scholars from Upen Baxi to M P Singh in the 90s. In fact, in one of its special issues, Baxi even claimed it to be the most philosophically inclined law journal in the country. Whether it still carries that tradition is open to debate.
