A Senate panel will hold a hearing this week to consider Congress’ role in federal rulemaking following a Supreme Court ruling last year that limited agency power.

Last June, the Supreme Court overturned the so-called Chevron doctrine, which has for decades given agencies license to interpret ambiguous laws. Nearly 14 months later, Congress is still mulling how the change impacts lawmakers.

On Wednesday, a Senate Homeland Security and Governmental Affairs subcommittee will convene for the latest congressional hearing on the matter. Lawmakers will hear from lawyers and former government officials on how legislation should evolve after Chevron.
