The incident last September has only come to light after it became widely known among locals.
The diplomatic protection officers had been patrolling outside the former Prime Minister's £4.3 million London townhouse.
They approached the man, who appeared to be drunk, urinating on Mr. Blair's front doorstep.
A scuffle ensued in the 3am incident and the police fired the 50,000-volt taser to incapacitate the Arab man so they could arrest him.
The unarmed suspect, Ayedh Alrashidi, who only speaks Arabic and understands little English, collapsed and was taken to a nearby hospital.
It was later revealed that Mr Alrashidi, 40, described as "a wealthy and peaceful man", is a government official from Kuwait.
He was charged with being drunk and disorderly and assaulting a police officer.
At a later hearing at Westminster Magistrates Court, an agreement was reached between the Crown Prosecution Service and his solicitor that Mr Alrashidi would be bound over to keep the peace for a year.
Mr Tablieh said: "Mr Alrashidi is a Kuwaiti national, who lives abroad. He doesn"t speak very good English. He is a peaceful man and he didn"t realise what was happening."
Mr Alrashidi had been staying with friends in a flat just ten minutes walk from Mr Blair's West London home in Connaught Square.
A friend of Mr Alrashidi said: "He didn"t deserve to be treated like that, he is a man who lives a life of luxury in Kuwait, as a respected government official. He didn"t realise he was outside Mr Blair's home."
A Scotland Yard police spokesman said: "A taser was deployed and a man was charged with assault and being drunk and disorderly."
