you can only run to the SCT for specific claims only, annex of the claim form here:
http://app.subcourts.gov.sg/Data/Files/ ... imForm.pdf
u may have confused yourself with the box named "a breach of landlord's obligation", meaning the tenant can only file at SCT if he wants to claim damages due to the old landlord's breach of contract before the TA's expiry.
a claim filed at SCT is to resolve
parties' to the contract's claim(s).
no where in it states that you can claim against a successor-in-title for specific performance of the clause, so of cos you need to go to subordinate courts for that.
hence i have said in my first initial posting, it is a clear cut breach of contract by the
landlord and that it is far easier (and cheaper) to claim from the landlord than to ask for specific performance.
SCT is also not the only place u can go to for claims, CASE is also empowered to handle landlord-tenant claims
