The Appellate Shield (Texas)
When an interlocutory order can't wait — or can't be appealed at all — Texas civil practice has two answers: MANDAMUS (the original proceeding) and SUPERSEDEAS (suspend enforcement while you appeal). Both are shown with their rules; the platform never predicts whether relief will be granted.
The mandamus shield (TRAP 52)
Texas civil practice's extraordinary lane — the un-appealable order gets original-proceeding review.
- 1
The gate question
No adequate remedy by appeal + a clear abuse of discretion — the In re Prudential balance (ANCHOR: verify before citing; anchors are pointers, never authored law).
In re Prudential Ins. Co. of Am., 148 S.W.3d 124 (Tex. 2004) — anchor

The petition
An original appellate proceeding seeking extraordinary relief — TRAP 52.1's own words — with the certified record and sworn statement the rule requires.
Tex. R. App. P. 52.1, 52.3, 52.7
- 3
Temporary relief
The appellate court may grant temporary relief pending its determination (52.10).
Tex. R. App. P. 52.10
Mandamus grounds are SHOWN as the doctrine's own tests with verify-flags — the platform never predicts a grant.
The supersedeas calculator (TRAP 24 + CPRC 52.006)
Suspension of enforcement pending appeal — the money-judgment security math is statutory.

Methods
Agreement, bond, deposit, or alternate security — TRAP 24.1's own menu.
Tex. R. App. P. 24.1

The money cap
Security = compensatory damages + interest + costs, but NOT MORE than the lesser of 50% of the judgment debtor's current net worth or $25 million — the statute's own ceiling.
Tex. Civ. Prac. & Rem. Code § 52.006(a)-(b); Tex. R. App. P. 24.2(a)(1)

Reduction for substantial economic harm
The trial court must lower the amount if the statutory security would cause the debtor substantial economic harm.
§ 52.006(c)
Net-worth inputs are the debtor's sworn numbers — the calculator traces arithmetic, never asserts a party's finances.
