But there have been growing gripes from all quarters that Smith has been going too far in seeming to want to also be Parliament's coach and commentator when his role should strictly be referee only.
When these tensions boil over in the House, Smith's exasperation with repeated points of order challenging his rulings can see him reply with a particularly cutting remark or putdown.
That was the case yesterday as MPs struggled to comprehend Smith's ruling that the phrase "position of hypocrisy" was okay parliamentary language.
His decision was a surprise as words such as liar and hypocrite have been considered out of order since Dick Seddon ruled the roost a century ago.
Labour frontbencher Clayton Cosgrove pleaded with Smith to offer some clarity and consistency in his rulings. Smith was merciless in response, saying he had given "reasonable clarity to people of reasonable intellect".
The jibe was too much for one of Cosgrove's colleagues. Trevor Mallard got to his feet to seek leave to move Peters' motion. Smith's blushes were saved by his National colleagues refusing leave.
Cosgrove got the last word, however. He determined revenge was a dish best served immediately. Speaking a few minutes later in the Wednesday general debate - and with Smith still in the chair - Cosgrove wove in a reference to an unnamed Minister of Education who lacking "intellect" and "smarts" had abolished the apprenticeship system in 1992. No prizes for guessing that the proud holder of the education portfolio in 1992 was one Lockwood Smith.
