Which of the following is an example of checks and balances? Select all that apply. The judicial branch can rule a new law unconstitutional.

The concept of checks and balances involves the ability of each branch of government to limit the powers of the other branches to prevent any one branch from becoming too powerful. Here are the examples from your list that illustrate checks and balances:

1. **The judicial branch can rule a new law unconstitutional.** (This is a check on the legislative branch by the judicial branch.)

2. **The legislative branch can override a veto.** (This is a check on the executive branch by the legislative branch.)

The other statements do not accurately represent checks and balances:

- **The judicial branch can veto presidential pardons.** (This is incorrect; the judicial branch does not have the power to veto pardons.)

- **The executive branch can impeach a Supreme Court Justice.** (This is incorrect; impeachment is a power of the legislative branch.)

- **The executive branch can declare war.** (While the executive branch has a significant role in military actions, declaring war is constitutionally a power reserved for Congress, providing another example of checks and balances.)

So, the correct selections that exemplify checks and balances are:

- The judicial branch can rule a new law unconstitutional.
- The legislative branch can override a veto.
