There are many within the Southside & Newington ward who are, or who have been, involved in having a statutory notice imposed on their property. Usually for tenements, the use of such repair notices has increased in recent years.
The city wide problems have been under investigation for some time and the March suspensions appear, at first blush, to be a result of management action regarding concerns. However, there is also a police enquiry ongoing. Beyond that there is not much else I can say at this stage - other than point you to other reporting of the matter e.g. this BBC item or this Scotsman article.
