I want to know the answer to the following question:
What action did The Sun take against Mahmood?
All the background I'm provided with is that "At her subsequent trial, the case against Tulisa collapsed at Southwark Crown Court in July 2014, with the judge commenting that there were "strong grounds" to believe that Mahmood had lied at a pre-trial hearing and tried to manipulate evidence against the co-defendant Tulisa.". Is that enough to answer the question?
Answer: no
