Sereno's an eyesore to the rest of the Supreme Court justices because:
1. She doesn't have trial experience, she's mostly a legal researcher and a teacher
2. At age 52, her tenure ends at 2030. This practically dashed the hopes of the senior members, like the ambitious Antonio Carpio of ever becoming Chief Justice in their career
3. Somewhat giving credence to the psyche report, Sereno has been making self-decisions on matters which requires en banc decisions. This has caused her to lock horns with Justice Teresita de Castro.
We all know why Noynoy Aquino mustered all the resources of the government to remove Renato Corona and replace him with Lourdes Sereno: the protection of Hacienda Luisita for the Cojuangco clan.
