Whatever you may think of the Irish constitution, and these people using it to their best advantage, the fact remains, it says what it says, and it stopped the police vacating the premises dead in its tracts. If the man is indeed in default of paying his loans with the bank, the government needs to legally deliver the warrant, and then evict the man.
NOTE: There is no moral argument in favor of someone taking out loans, not paying them back and then holding onto the property. That’s in itself, theft.

Ireland: Man Uses Constitution to Stop Courts at Gate from Repossessing his Home.
