What Parliamentary procedure is this? PM announced Hougang Seat VACANT & then Ask Yaw

[tun_dr_m]

Ass Loong Son told the TV that the Hougang Seat is already VACANT 1st. Then they sent letter to ask Yaw Shin Leong weather he will appeal is expel (with that date line)?

What type of procedure is this? Cart before Horse?:oIo:

If Yaw appealed then how? Is Loong's dick (if any) stuck within his own mouth? Huh?
