Najib is quoted as saying that, "This will allow the public to give their comments, engage them, and if we find it necessary to fine tune it, we'll do so".
He stressed that if the government decided to introduce the GST in Malaysia, it would do so "very gently".
"It's not going to be an abrupt introduction," Najib said, adding that if the GST materialised, the rate would not burden the poor or middle-class Malaysians.
"And, it would not lead to inflation," he added.
Firstly, by tabling a Bill, the legislative process has commenced. There's a First Reading, then, there's a Second Reading and, then, a formal Third Reading whereupon the Bill becomes an Act of Parliament. The speed of the legislative process is at the discretion of the coalition in power.
A sincere effort at allowing public input should involve putting up the draft Bill in a suitable website, perhaps by the Treasury where comments can be received in an orderly fashion.
Tabling a Bill is a fait accompli which is, by definition, "an accomplished, presumably irreversible deed or fact".
Secondly, all consumption taxes has an inflationary effect even if it is a once-off effect.
Thirdly, "not be(ing) abrupt" is a relative view of the Prime Minister. If by "not be(ing) abrupt" he means that there will be lots of publicity about the Bill (and, therefore, following the reasoning, there should not be any psychological shock), then, he may be correct. But, the moment the Bill becomes an Act of Parliament and, it is given the Royal Assent and, is given a Commencement Date, then the implementation will still inevitably be felt by the public and the Malaysian economy as an "abrupt" phenomenon.
The question, therefore, is why the draft Bill should be tabled in Parliament when it can easily be posted at Treasury's website where public opinion can be sought for a period of, say, 6 months?
