With respect to the September 15, 2020 webinar on "how to cross examine vocational experts" Meredith Marcus and Dana Duncan as speakers were really focused on the social security practice with respect to this topic. The other speaker, Dennis O'Brien, on the substance of cross examination was more general and as his practice is not limited to social security disability but includes also apparently personal injury and workers compensation cases. He spoke about ethics as well and again this presentation was broader than the so security disability practice which actually has some unique aspects to it whereby the Social Security Administration, for example, requires attorneys to submit "all evidence" even if unfavorable and there are special procedures about withdrawing as the attorney. Mr. O'Brien, for the ethics portion of his talk did you have a concrete example of a colleague who fortunately had documented well in the file advice to the client when years later it was inquiry made about that former client's conduct with Social Security. Meredith Marcus did over some sample testimony with respect to cross examine the VE's that was helpful and Dana Duncan gave a number of examples of applying the claimant's specific case to the VE testimony. I did have some technical issues during the webinar and that I would lose the audio but that may be I need to improve however I connected with NBI for this seminar. The tech support of NBI was helpful when I called and basically I just had to get out of the seminar and log back into the link I received an email but I had to do this several times throughout the program when the speaker would still be on the screen but I could not hear the presentation.
