At the end of March 2010, OfCom announced a change to BSkyB's licence which allows it to broadcast Sky Sports 1 & 2. That change obliged BSkyB to wholesale those services to other interested broadcasters so that, for example, football fans weren't forced to have both BT's and Sky's services in order to watch all televised matches. Further, so that BSkyB couldn't simply offer to wholesale those services at unaffordable prices, OfCom ruled that the wholesale price of BSkyB's 'Standard Definition' services should be determined by OfCom (although BSkyB would still be free to charge what it liked for the 'HD' versions of those services).
BSkyB appealed against the ruling and, the following month, the initial ruling was varied by an Interim Relief Order, which effectively left BT without access to BSkyB's channels.
So BT then applied to vary the Interim Relief Order to allow it to broadcast Sky Sports 1 and 2 over its internet-based services. (i.e. via its YouView and Cardinal set-top boxes).
For the next four years there were legal arguments about whether BT actually had the right to seek a variation to the Interim Relief Order. The Competition Appeal Tribunal has now ruled that BT has such a right and has agreed to amend the Interim Relief Order so that BSkyB will be required to wholesale Sky Sports 1 and 2 for broadcast on BT's internet-based services. As a condition of that agreement, BT is obliged to continue making BT Sport available for broadcast by BSkyB.
However all of that only refers to the
Interim Relief Order, which was put in place when BSkyB first appealed about the changes to its licence conditions. That appeal is still ongoing, so there may yet be further developments in the dispute.
My summary is based upon this one

but with an attempt to make it less technical (and to offer a bit of background explanation). If you're feeling brave, you can wade through this lot for a detailed explanation:
