We revisit the limits on R-parity violation in the minimal supersymmetric standard model. In particular, we focus on the high-scale supersymmetry scenario in which all the sparticles are in excess of the inflationary scale of approximately 1013 GeV, and thus no sparticles ever come into thermal equilibrium. In this case, the cosmological limits, stemming from the preservation of the baryon asymmetry that have been previously applied for weak-scale supersymmetry, are now relaxed. We argue that even when sparticles are never in equilibrium, R-parity violation is still constrained via higher dimensional operators by neutrino and nucleon experiments and/or insisting on the preservation of a nonzero B-L asymmetry.
