> in India, it is illegal for an MP to vote against the party line

That is not true at all. Anti-defection law is applied when elected officials run on a party and once elected decide to change their party affiliation. Not for individual bills.

The Anti-Defection Law can very much be applied if a legislator votes against a party whip, even for a bill. There are calls to limit its applicability only to votes on the government, but that is currently not the case.

Quoting from PRSIndia [1]:

Does the anti-defection law affect the ability of legislators to make decisions?

The anti-defection law seeks to provide a stable government by ensuring the legislators do not switch sides. However, this law also restricts a legislator from voting in line with his conscience, judgement and interests of his electorate. Such a situation impedes the oversight function of the legislature over the government, by ensuring that members vote based on the decisions taken by the party leadership, and not what their constituents would like them to vote for.

Political parties issue a direction to MPs on how to vote on most issues, irrespective of the nature of the issue. Several experts have suggested that the law should be valid only for those votes that determine the stability of the government (passage of the annual budget or no-confidence motions).

It's not illegal. But that ensures their eviction from the party and can potentially destroy their political career.
