The Short Version
The claim accurately reflects the general direction of reform recommendations from these three bodies — all broadly favored restricting disqualification to government-survival votes — but materially overstates their findings. None of the primary sources explicitly document a shared conclusion that the law "weakened intra-party democracy." The NCRWC also defended the anti-defection law's mandate rationale, and the specific diagnostic framing attributed to all three bodies derives from secondary PRS syntheses rather than the primary reports themselves.
