Template:Suspension v Settlement Disruption
While there is overlap between Settlement Disruption Events and Suspension Events (in that both are things beyond the parties’ control) Suspension Event, being narrower and related to the failure of official infrastructure, trumps Settlement Disruption Event where they both apply to the same event. Generalia specialibus non derogant, I suppose.
Note the Long-Stop Date concept, which references 1 June in a year following a set of seemingly arbitrary two-year spells in the Fourth Compliance Period and relates only to Suspension Events, not Settlement Disruption Events, and also appears to bear no relation at all to the Reconciliation Deadline at the end of April in each year.
