Certificate is good... aka will be good retro active pending the passage of the bill. As far as I am aware which is a little more than some, no one has been refused in any county yet on an old certificate, but it COULD happen under the new wording from last year.
SIS is a killer in mo. I suppose it depends on what it is for, but the law reads plead guilty to or was convicted of a misdemeanor, if it carries a penalty of one year or more... and an SIS is a guilty plea.
I am sure hoff has the statute at his finger tips and may come along and paste it for us.
A lot of folks fall under the misconception that an SIS served flawlessly drops from their record, it does not and will stop a Missouri permit depending upon what it is for sir.
