Did my hon. Friend consider specifying a longer period than three years? Being a lawyer, like me, he will realise that if an environmental catastrophe was not caused by a third party, things could conceivably still be grinding through the courts after three years. Did he consider having perhaps a six-year period or a rolling cost-benefit analysis? It is not beyond conception that in three years no catastrophe would have happened—we certainly hope it would not—so did he consider other time periods?
