I recall that Joe indicated that approximately 25% of visa applications are double checked. And Terpe has made the point below.....

Just take an example of UKBA Visa's, should the ECO have every single visa appraisal completely checked by a checker? What about checking the checker and so on?
Where does the line get drawn between cost of process, cost of staff employment, time taken etc etc.
I feel sure questions would be raised about efficiencies and taxpayer money. Especially taking considering all life costs of public sector employees.
Upon review I would suggest that if 50% of the Spouse and Fiancee Visa application fees cover the costs of processing the application then there is more than enough money available to pay for a double check.

I would propose that given that 98% of Spouse and Fiancee visas are successful, then why not doublecheck all of the refusals. It would save so much hassle for all parties if they did. And wouldnt cost them a lot of time and money.

I have first hand experience of this sort of thing, but in another sphere and believe you me it doesn't take much more than 5 minutes to double check with a trained eye, with all the material in front of you. I don't think checking the checker would be necessary if both the original assessor and the checker were competent and Competent - (There is a difference between the two). A quick squint by the checker, in Marcos application case, should have set the alarm bells going and hopefully a re-appraisal of that refusal. It isn't necessary to double check absolutely every application. All the designated responsible person need do is say " before you send out a refusal, I want to see it first ". Simples.

And I don't subscribe to the idea at all that these guys are pouring over these applications for weeks at a time. For 800 quid they should get it right first time.
