It certainly seems that an experienced and quaified plumber would not just put a vertical rise for no reason. To say nothing about the fact that a cleanout at that point would be a waste of good pvc.
But then again...if the same guy that did the 2 supply lines did the area of concern...well you may need to change the statement from experienced and quaified plumber to amature...at best!
One thing I noticed, I think....is that the dishwasher drain pipe running along the top? Is there another sink to the right of this photo?
If yes, then you also should call out: "Air gap for dishwasher is by means of improper High-Loop." I am sure you know that the proper method...but here is a drawing for your report:
One last thing...I would deffinately call out "insufficient and/or improper support of the supply lines."
Now, if the item I have marked with CAUTION in my photo is the hose spay...then I would add that "hose spay tubbing may become entangled and cause further damage."
Just my 2 cents worth.

Good cut-away representation of an air-gap installation. Unfortunately, there is no way that both 20" and 24" are = to 61.0 cm. Oops. Freaking metric heads.

I use this drain set up alot on island sinks.If the drain is 2 sizes larger than the trap size it is legal. Here the trap is 1-1/2 and drain is 3". The reason is there is enough volume in the 3" that the air can move freely in the top half.
The reason for the 3" cleanout is becouse you cant get a large enough snake to clean well by just removing the trap.

I do not have another angle on this Harvey. Yes the back line is the dishwasher line and the front silver is the conduit to disposal at other basin.
This is not an island though,
can anyone reference me a code for venting or that this arrangement may be incorrect?
I couldn't find anything in FBC but then again its search function (the cd) isn't very good

As far as the unexplained lack of AAV installation, I am not sure where to go there.
What year was the house built? Not really that it matters as long as "sufficient venting is supplied".
I think I would go with what Robert says...it would seem that this is a "trade trick" from someone...what I am not sure of however is if it causes a "sewer gas trap" and a "vacuum"...but then again I may be over analyzing it.
If you still feel that little check in your spirit that there is something not right or that we are not seeing...simply follow the "unsupported supply lines and the improper High-Loop for the dishwasher" with "further evaluation by licensed pluming contractor on non-industry standard installation and/or repair noted under sink".
By the way, will you be joining us on Sat Aug 28, for what has turned out to be one the largest and best NACHI Meetings? Bring your spouse...as it stands, about 90% have signed up with their spouses. Combine it as a weekend getaway!

OOOPS! You are correct Christopher…when I copied over the arrows from the rear…I forgot to onvert the inches over to centimeters…the proper result is 51cm.
Here is a corrected image
Thanks for keeping me honest Christopher

Shawn,
Looks like there should be an AAV there, that clean out certainly won't do much good like that.

I have been going through the IRC and can’t seem to find anything that supports what I found
… the drain pipe was a bit larger…
(no I didn't measure because I was planning on going back to take another look...but got sidetracked)
Thanks for all the input!

The specs on the high loop are very useful. It seems odd that the two minimum heights are specified, but not a minimum height from the drain connection to the top of the loop (marked as ?? in my diagram). Is there a minimum for that distance? If not, there wouldn’t be a requirement for a loop at all – the drain could be at the highest point. Can I extrapolate a minimum of 4 inches (10 cm)?

From the FBC 2001 as revised 2002 and 2003
COMBINATION WASTE AND VENT SYSTEM. A specially designed system of waste
piping embodying the horizontal wet venting of one or more sinks or floor
drains by means of a common waste and vent pipe adequately sized to provide
free movement of air above the flow line of the drain.
?P909.1 Wet vent permitted. Any combination of fixtures within two
bathroom groups located on the same floor level are permitted to be vented
by a wet vent. The wet vent shall be considered the vent for the fixtures
and shall extend from the connection of the dry vent along the direction of
the flow in the drain pipe to the most downstream fixture drain connection
to the horizontal branch drain. Only the fixtures within the bathroom
groups shall connect to the wet-vented horizontal branch drain. Any
additional fixtures shall discharge downstream of the wet vent.
?P909.2 Vent connection. The dry vent connection to the wet vent shall be
an individual vent or common vent to the lavatory, bidet, shower or bathtub.
?P909.3 Size. The wet vent shall be of a minimum size as specified in
Table P909.3 based on the fixture unit discharge to the wet vent.
