It's a summary of a case heard in the Court of Common Pleas in Michaelmas Term, 7/8. Elizabeth (= 1565), published in a volume of law reports. To summarise, as I understand it ...
John Dryland was tenant for life in a property, with the reversion going to
Thomas Serles, one of his executors. But meanwhile Dryland leased the property to
Francis Swain for 15 years, with a covenant guaranteeing Swain’s peaceful occupation. Swain entered on the property, Dryland died, and Serles (as Dryland’s executor) then ejected Swain. Swain then brought an action of breach of covenant against Serles and Strensham, but judgment was given in favour of the executors. The case seems to turn on whether the terms of a covenant can be held to prevail after the death of a tenant for life. The report references a similar case that was heard in Trinity Term, 22. Elizabeth (= 1580).
The common pleas for 1565 seem not to have been indexed yet, so to find the original you would have to trawl through the online images (series CP 40) in Michaelmas 1565 to find rotulet 1137, and then it will be in Latin.
