Do you think Duke would really give a scholarship to someone who signed a binding agreement and then decides to try to hold them over a barrel? I would think that Duke would be more than willing to say have fun toiling around for the next year.
Zero chance Duke will give a scholarship by waving an HLS acceptance in their face. ZERO. It is an absurd thing to do. Some people on this site just give the most terrible advice that it boggles my mind and actually makes me angry!!!
Duke is far more likely to REVOKE your ED than to give you one cent of scholarship money if you do that, and not only that, they will probably tell other schools to blacklist your ass.
Why zero chance? Duke is < Harvard, they're aware of that fact, and schools give out scholarship money based on your ability to get into better schools. The ED factor is unique here, but I fail to see why that absolutely precludes the possibility of the OP shaking some cash out of Dook by leveraging the H acceptance. Sure OP might just end up sitting out a year, but if they're fine with that, it's no big deal.
As for the quality of my advice, aren't you still working on the LSAT? I've done the application process myself and I've seen more than a few people leverage acceptances at better schools into scholarships at lesser schools. Granted I've never seen it with an ED app, but I also don't know anyone that got accepted into somewhere on ED, so I really don't know if it would work or not. And besides, all I said was that the OP could try it, not that they should.
Lol at the mafioso outlook on law schools. You're not going to get blacklisted because you decided not to go to school for a year after asking for scholarship money. This is a belief born of the myth and fear propagated by 0Ls. OP might not get back into Duke if they break their ED, but they're not going to be blackballed either.
Whether you have gone through the actual application process (once) does not in any way legitimize your advice or signify that you are in a better position than me to offer advice. Early Decision is binding. It means that if you get in, you must immediately withdraw all other applications. It means that if you get in you have absolutely no opportunity to accept an offer from another school. Telling Duke that you will not go at all unless they give you scholarship money because you have a Harvard acceptance is ridiculous. While he won't be blacklisted per se, it is still possible that the admissions office shares this kind of behavior with other schools. Schools do talk to each other. If he were to take your advice and go to Duke waving that HLS acceptance in their face, and then he decides after all not to go to Duke after Duke immediately denies his request for scholarship money, there is a great chance that Duke admissions will be making some calls. This will not help OP in the following admissions cycle.
There was an applicant who posted on LSD a few years ago. He posted significant identifying information on these boards. Based off what he posted here, Texas Law believed that his app to their school contained misleading information in regards to his race/ethnicity. Texas viewed his LSN and then contacted his other schools about what they felt might be an impropriety in the application. The point is, I have no clue whether Duke would contact other schools or if this would be a reason for Duke to contact other schools - but schools do talk and share information. Considering that one who signs an ED is required to immediately withdraw all applications from all schools, leveraging for money seems like a particularly immoral decision.
