How it applies
Common Examples
6
Tool Insertion During Break-In
Samuel Soto inserts a screwdriver through a window to unlatch it and then reaches his arm inside the home. Because the tool was used solely to gain entry rather than to commit the intended felony, the entry element of burglary is not satisfied under the governing rule.
Post-Closing Repair Dispute
Simone Sanders accepts the deed at closing without any repair covenant appearing in the deed. After discovering needed roof repairs, her contract claim fails because the deed has become the sole measure of the seller's obligations.
Congressional Power Enumeration
Steven Silva challenges a federal statute regulating purely intrastate activity. The statute is upheld only to the extent it rests on one of the enumerated powers listed in the constitutional grant. No unenumerated authority supplies an independent basis.

Initial Disclosure of Witnesses
Sydney Santos serves initial disclosures that omit a key fact witness. The omission is harmless only because the witness's identity would be used solely for impeachment and therefore falls outside the mandatory disclosure obligation.
Trust Account Service Charges
Sasha Stone deposits a small personal sum into the client trust account. The deposit is permissible because it is made for the sole purpose of covering bank service charges and does not exceed the amount necessary for that purpose.
Concurrent Fee Tail Estate
Sylvia Santos conveys property creating a fee tail estate to be held by two grantees. The estate may validly exist as tenants in common under the applicable rule governing concurrent ownership of such estates.

Frequently Asked
4
When does insertion of a tool satisfy the entry element of burglary?+

A party must disclose the name and contact information of any individual likely to have discoverable information the party may use to support its claims or defenses. Disclosure is not required when the use would be solely for impeachment.
