Any final approval of Charter Communication’s planned acquisition of Time Warner Cable and Bright House Networks will likely not come before next summer, as regulators in California decide to take a closer look at the blockbuster merger deal that would make Charter the second largest cable company in the country.

An administrative law judge is contemplating the merger’s impact on California, and a decision is unlikely to come before May 2016, with a final vote of the California Public Utilities Commission tentatively scheduled for June 16th. The judge agreed with consumer groups that the deal warrants evidentiary hearings — a sign the deal deserves additional scrutiny.

New York State’s Public Service Commission is also still reviewing the transaction, although it is expected to render a decision within the next few months. On the federal level, the FCC has also not held back, recently requesting answers to a number of questions regarding John Malone’s involvement in the future of “New Charter.” Malone remains Charter’s biggest single shareholder and could wield considerable control over New Charter’s operations. Considering Malone’s long history of antagonizing customers and engaging in what lawmakers called anti-competitive behavior during his realm at Tele-Communications, Inc. (TCI), regulators may not want to see history repeat itself.

What was originally anticipated by industry observers to be an ‘easy approval,’ is now looking more like Comcast’s failed bid for Time Warner Cable, as regulators seem to be in no hurry to give Charter’s deal a green light.

If regulators do ultimately approve the deal, it is likely to come with a number of conditions designed to at least temporarily protect consumers and competitors. Stop the Cap! argued in filings with state and federal regulators Charter’s proposal was uncompelling and consumers were unlikely to benefit from the deal. Time Warner Cable’s ongoing Maxx upgrade program delivers faster Internet speeds and better service than Charter’s more modest proposal offering upgrades up to 100Mbps. Time Warner Cable Maxx offers customers up to 300Mbps broadband for the price the company now charges for 50Mbps.
