the act was invalidated and the Home Rule movement collapsed because the government over-rode the promised discussion on how partition should be implemented by unilaterally making it permanent.

When did that happen Jim? Lloyd George's discussions and correspondence with both Redmond and Carson took place in mid-to-late summer 1916 didn't they? And the Rising took place when?

When did they {The British Government} unilaterally make partition permanent? You incorrectly stated that Lloyd George wrote to Carson guaranteeing permanent partition, but he did no such thing did he - The letter written to Carson assured Carson any agreement reached would not put Ulster in the position that it could be forced into any union against its will - different thing entirely.

Also if the British Government had unilaterally made partition permanent in July 1916 could you explain why the 1920 Government of Ireland Act still mentions temporary partition?

Furthermore if the British Government had unilaterally made partition permanent in July 1916 could you explain why the clause relating to Northern Ireland was required in the Anglo-Irish Treaty of 1921?

It could of course all be down to fact that you are talking a complete and utter load of bollocks.
