"ALARP (Temporal)"
I believe this relates to a policy documented by the MAFTR (MAA predecessor) around the mid-noughties which said that so long as you had a current effective programme in place to address a risk, the hazard could be regarded as ALARP. While the creation of the "Temporal ALARP" concept was regarded as slightly unnecessary, it was recognised that it fitted with the understanding of the ALARP concept. In rough terms, 'instant' risk mitigations may not be possible and it wasn't judged reasonable to abandon defence of the realm, therefore a court would accept that the existence of a current mitigation programme was an acceptable approach.
