A more thorough explanation:

Definition: To remove a case from the docket by order of the court or to announce that an item has been sold at an auction.

Example: The judge decided to strike off the case due to lack of evidence. At the auction, the auctioneer struck off the painting to the highest bidder.

Explanation: When a court strikes off a case, it means that the case is no longer being considered and will not proceed to trial. In an auction, when the auctioneer strikes off an item, it means that the item has been sold to the highest bidder. Both examples illustrate the action of removing something from consideration or announcing its sale.
