We sort of sneaked it in, but we now have online over 200 of DHCR Opinion Letters from 2008 and 2009. You can access them at http://www.tenant.net/DHCR_info/Opinion_Letters/ -- and they will soon be on the green menu at the top of the page.
There are many more to obtain, but this is a good start.
We would like to thank the individual who provided these after obtaining paper copies from DHCR. The scanning and indexing process would have gone quicker had DHCR not lied when they falsely stated there is no index for these opinions.
