Reforms designed to curb the "compensation culture"are set to be debated by MPs after the Compensation Bill cleared the House of Lords on Monday.
Peers passed the Bill despite uncertainty about the initial impact of a new defence against claims of "desirable activity".
Tory spokesman Lord Hunt of Wirral warned: "The courts will have to build up case law relating to this new concept of 'desirable activity' and we cannot be sure precisely where that will lead.
"There is also a danger that it may be applied unevenly. However, a half-full cup seems preferable to an empty one."
The Bill will now come before the Commons at a date to be decided by Leader of the House Geoff Hoon.
