appeal no use ?? got use la .... can make us appeal for 2 reason
...
1) Esp for this case, most prob they can consider this, as the
driver do not know and morever the signboard didn't state. in most
cases where driver claim that they didnt know then appeal, ura/hdb
will reply tat, u have the check the board first and if it does
state, then it's our fault. in this threadstarter case, mentioned
that the board didn't state .. so ... ya ... should be able to
..
2) Delay payment - nowadays in other cases which we will most prob
loose, appeal are only used to extend grace period dateline to pay
off the summon .. for instance if they are given 7 days grace to
pay, just let's say a kid above 18 has no $$$ on within that days
to pay off, as his driving his dad car and would like to clear the
summon before his dad know, on the last day of the 7th day, he
could make the appeal, then authority will take 10 days to give the
result, upon rejected, do 2nd time appeal, which will take another
10 days, by the time second time rejected, it would already be a
total of 27 days, by then he could have save up and pay off the
summon ..
