Procedure
I was working Ground Control and was not a part of the situation that happened.  The Field level manager (FLM) was giving a skill check on LC1/LC2.  Aircraft X was on a 4 mile final to ILS-RWY16R when he responded to TCAS-RA and started climbing. The Developmental was not sure of what to do and was told to tell Aircraft X by the FLM; to execute the missed approach and to have descend to 1;700 MSL.  The 1700 MSL crossing restriction is for the BUR arrivals passing over VNY airport at 2;700MSL. Aircraft X was 3 plus miles north climbing (approx. 3;000 MSL) and off the glide slope.  Aircraft X was made to descend to 1;700 below the MVA.  The VNY missed approach procedures are just bad and there is always confusion as to what to do.  How can a class delta tower tell an IFR aircraft aborting an approach be told to descend below the MVA?VNY needs more exact procedures on what to do.  Calling the sector and awaiting a reply while aircraft converge is dangerous.  The missed approach should also follow the CANOG9 departure SID to the west away from the BUR traffic instead of to the east.
VNY Ground Controller reports of an observation where an aircraft receives an RA on final and is told to descend below the MVA to fix the situation.
